programacion - modificar navigation drawer android studio

¿Cómo cambiar la actividad en el botón de navegación inferior clic?

Question

Quiero usar la barra de navegación inferior en mi aplicación de Android existente, pero el problema es que todas las pantallas son actividades, es posible cargar la actividad sin ocultar la barra de navegación inferior.

ejemplo: activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.NestedScrollView
android:id="@+id/myScrollingContent"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Your loooooong scrolling content here. -->
</android.support.v4.widget.NestedScrollView>
<com.roughike.bottombar.BottomBar
android:id="@+id/bottomBar"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="bottom"
app:bb_tabXmlResource="@xml/bottom_bar"
app:bb_behavior="shy"/>
</android.support.design.widget.CoordinatorLayout>

esta es mi actividad base,

MainActivity.java

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomBar bottomBar;
bottomBar = (BottomBar) findViewById(R.id.bottomBar);
bottomBar.setOnTabSelectListener(new OnTabSelectListener() {
@Override
public void onTabSelected(@IdRes int tabId) {
if (tabId == R.id.matching) {
Log.i("matching","matching inside "+tabId);
Intent in=new Intent(getBaseContext(),Main2Activity.class);
startActivity(in);
}else if (tabId == R.id.watchlist) {
Log.i("matching","watchlist inside "+tabId);
Intent in=new Intent(getBaseContext(),Main3Activity.class);
startActivity(in);
}
}
});
}
}

Main2Activity

public class Main2Activity extends MainActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main2);
NestedScrollView dynamicContent = (NestedScrollView) findViewById(R.id.myScrollingContent);
View wizard = getLayoutInflater().inflate(R.layout.activity_main2, null);
dynamicContent.addView(wizard);

Main3Actividad

public class Main3Activity extends MainActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main3);
NestedScrollView dynamicContent = (NestedScrollView) findViewById(R.id.myScrollingContent);
View wizard = getLayoutInflater().inflate(R.layout.activity_main3, null);
dynamicContent.addView(wizard);
}
}

manifiesto

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.bottom.bottomnavigation">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".Main2Activity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity" />
<activity android:name=".Main3Activity"></activity>
</application>
</manifest>

Answer 1

Con Activity , debes declarar e BottomBar ese BottomBar cada vez que cargues esa activity .

Con tu problema, mi respuesta es NO .

Por cierto, puedes usar Fragment que te ayuda a resolver esto bastante bien.

Es hora de aprender algo nuevo, hermano.

EDITAR

Traes Fragment dentro de solo 1 Actividad. Y deje que BottomBar dentro de la Activity mientras todos los demás vean y los datos se configuren dentro del Fragment .

¡Solo inténtalo!

Answer 2

He resuelto este problema de la siguiente manera:

1.Crear una BaseActivity con la barra de navegación inferior.

 package com.example.apple.bottomnavbarwithactivity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class BaseActivity extends AppCompatActivity {
RadioGroup radioGroup1;
RadioButton deals;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
radioGroup1=(RadioGroup)findViewById(R.id.radioGroup1);
deals = (RadioButton)findViewById(R.id.deals);
radioGroup1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(RadioGroup group, int checkedId)
{
Intent in;
Log.i("matching", "matching inside1 bro" + checkedId);
switch (checkedId)
{
case R.id.matching:
Log.i("matching", "matching inside1 matching" + checkedId);
in=new Intent(getBaseContext(),MatchingActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.watchList:
Log.i("matching", "matching inside1 watchlistAdapter" + checkedId);
in = new Intent(getBaseContext(), WatchlistActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.rates:
Log.i("matching", "matching inside1 rate" + checkedId);
in = new Intent(getBaseContext(),RatesActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.listing:
Log.i("matching", "matching inside1 listing" + checkedId);
in = new Intent(getBaseContext(), ListingActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.deals:
Log.i("matching", "matching inside1 deals" + checkedId);
in = new Intent(getBaseContext(), DealsActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
default:
break;
}
}
});
}
}

Diseño de BaseActivity llamado base_activity.xml

 <LinearLayout
android:layout_width="match_parent"
android:layout_height="56dp"
android:elevation="10dp"
android:background="@color/white"
android:id="@+id/bottonNavBar"
android:paddingTop="5dp"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:foregroundGravity="bottom">
<RadioGroup
android:id="@+id/radioGroup1"
android:gravity="center"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="horizontal"
android:baselineAligned="false">
<RadioButton
android:layout_width="match_parent"
android:gravity="center"
android:layout_height="match_parent"
android:text="Matching"
android:layout_weight="1"
android:button="@null"
android:padding="2dp"
android:checked="false"
android:textSize="12sp"
android:drawableTop="@drawable/selector_matching"
android:textColor="@drawable/selector_nav_text"
android:id="@+id/matching"/>
<RadioButton
android:layout_width="match_parent"
android:gravity="center"
android:layout_height="match_parent"
android:button="@null"
android:layout_weight="1"
android:padding="2dp"
android:checked="false"
android:textSize="12sp"
android:drawableTop="@drawable/selector_watchlist"
android:textColor="@drawable/selector_nav_text"
android:id="@+id/watchList"
android:text="Watchlist"/>
<RadioButton
android:layout_width="match_parent"
android:gravity="center"
android:layout_height="match_parent"
android:id="@+id/rates"
android:button="@null"
android:paddingTop="5dp"
android:paddingBottom="2dp"
android:paddingLeft="2dp"
android:paddingRight="2dp"
android:layout_weight="1"
android:checked="false"
android:textSize="12sp"
android:drawableTop="@drawable/selector_rates"
android:textColor="@drawable/selector_nav_text"
android:text="Rates"/>
<RadioButton
android:layout_width="match_parent"
android:gravity="center"
android:layout_height="match_parent"
android:button="@null"
android:padding="2dp"
android:checked="false"
android:layout_weight="1"
android:textSize="12sp"
android:drawableTop="@drawable/selector_deals"
android:textColor="@drawable/selector_nav_text"
android:id="@+id/deals"
android:text="Deals"/>
<RadioButton
android:layout_width="match_parent"
android:gravity="center"
android:layout_height="match_parent"
android:button="@null"
android:padding="2dp"
android:checked="false"
android:layout_weight="1"
android:textSize="12sp"
android:drawableTop="@drawable/selector_listing"
android:textColor="@drawable/selector_nav_text"
android:id="@+id/listing"
android:text="Listing"/>
</RadioGroup>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/dynamicContent"
android:orientation="vertical"
android:layout_marginBottom="56dp"
android:background="@color/white"
android:layout_gravity="bottom">
</LinearLayout>

2. Amplíe BaseActivity en toda la actividad que desee abrir en la parte inferior del botón de navegación y también necesita inflar los diseños de la actividad. Por ejemplo, he creado cinco actividades de muestra.

i] MatchingActivity.

 package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
//extends our custom BaseActivity
public class MatchingActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_matching);
//dynamically include the current activity layout into baseActivity layout.now all the view of baseactivity is accessible in current activity.
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_matching, null);
dynamicContent.addView(wizard);
//get the reference of RadioGroup.
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.matching);
// Change the corresponding icon and text color on nav button click.
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_matching_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}

ii] WatchlistActivity

 package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class WatchlistActivity extends AppCompatActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_watchlist1);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_watchlist1, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.watchList);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.favourite_heart_selected, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}

iii] TasasActividad

 package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;

public class RatesActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.activity_rates);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_rates, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.rates);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_rate_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}

iv] ListingActivity

 package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class ListingActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_listing);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_listing, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.listing);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_listing_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}

v] DealsActivity

 package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class DealsActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_deals);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_deals, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.deals);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_deals_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}

Nota: asegúrese de que maneja la prensa trasera correctamente. No he escrito ningún código para la prensa trasera .
