recuperar - Notificación de distintivo sobre la barra de herramientas de alternar cajón-Android
desaparecio mi barra de notificaciones android (5)
Basado en la respuesta de TDSoft, puede acortar el procedimiento aún más extendiendo DrawerArrowDrawable.
Paso 1: (Excepto por DrawerArrowDrable, básicamente igual que la clase Badge de TDSoft).
public class BadgeNavigationDrawable extends DrawerArrowDrawable{
private float mTextSize;
private Paint mBadgePaint;
private Paint mBadgePaint1;
private Paint mTextPaint;
private Rect mTxtRect = new Rect();
private String mCount = "";
private boolean mWillDraw = false;
/**
* @param context used to get the configuration for the drawable from
*/
public BadgeNavigationDrawable(Context context) {
super(context);
setColor(context.getResources().getColor(R.color.accent));
mTextSize = dpToPx(context, 8); //text size
mBadgePaint = new Paint();
mBadgePaint.setColor(Color.RED);
mBadgePaint.setAntiAlias(true);
mBadgePaint.setStyle(Paint.Style.FILL);
mBadgePaint1 = new Paint();
mBadgePaint1.setColor(Color.parseColor("#EEEEEE"));
mBadgePaint1.setAntiAlias(true);
mBadgePaint1.setStyle(Paint.Style.FILL);
mTextPaint = new Paint();
mTextPaint.setColor(Color.WHITE);
mTextPaint.setTypeface(Typeface.DEFAULT);
mTextPaint.setTextSize(mTextSize);
mTextPaint.setAntiAlias(true);
mTextPaint.setTextAlign(Paint.Align.CENTER);
}
@Override
public void draw(Canvas canvas) {
super.draw(canvas);
if (!mWillDraw) {
return;
}
Rect bounds = getBounds();
float width = bounds.right - bounds.left;
float height = bounds.bottom - bounds.top;
// Position the badge in the top-right quadrant of the icon.
/*Using Math.max rather than Math.min */
// float radius = ((Math.max(width, height) / 2)) / 2;
float radius = width * 0.15f;
float centerX = (width - radius - 1) +10;
float centerY = radius -5;
if(mCount.length() <= 2){
// Draw badge circle.
canvas.drawCircle(centerX, centerY, radius+9, mBadgePaint1);
canvas.drawCircle(centerX, centerY, radius+7, mBadgePaint);
}
else{
canvas.drawCircle(centerX, centerY, radius+10, mBadgePaint1);
canvas.drawCircle(centerX, centerY, radius+8, mBadgePaint);
}
// Draw badge count text inside the circle.
mTextPaint.getTextBounds(mCount, 0, mCount.length(), mTxtRect);
float textHeight = mTxtRect.bottom - mTxtRect.top;
float textY = centerY + (textHeight / 2f);
if(mCount.length() > 2)
canvas.drawText("99+", centerX, textY, mTextPaint);
else
canvas.drawText(mCount, centerX, textY, mTextPaint);
}
/*
Sets the count (i.e notifications) to display.
*/
public void setCount(String count) {
mCount = count;
// Only draw a badge if there are notifications.
mWillDraw = !count.equalsIgnoreCase("0");
invalidateSelf();
}
@Override
public void setAlpha(int alpha) {
// do nothing
}
@Override
public void setColorFilter(ColorFilter cf) {
// do nothing
}
@Override
public int getOpacity() {
return PixelFormat.UNKNOWN;
}
private float dpToPx(Context context, float value) {
Resources r = context.getResources();
float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, value, r.getDisplayMetrics());
return px;
}
}
Paso 2: Eso es todo lo que necesita, si necesita actualizar el ícono de su gaveta de navegación, llame: todos sus eventos se conservarán.
BadgeNavigationDrawable drawerIcon = new BadgeNavigationDrawable(MainActivity.this);
drawerIcon.setCount(String.valueOf(count));
mDrawerToggle.setDrawerArrowDrawable(drawerIcon);
mDrawerToggle.syncState();
Quiero notificar al usuario sobre un nuevo mensaje no leído en la aplicación al que se puede acceder a través del cajón de navegación. Estaba pensando en la insignia de notificación que algo similar a Apple tiene pero sobre el cajón para alternar en la barra de herramientas.
¿Cómo puedo lograr eso?
Logro esto agregando un TextView
a mi diseño principal con la orientación del interruptor. en mi mainactivity.xml agregué esto
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/badge_ham"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="26dp"
android:layout_marginTop="14dp"
android:textSize="9sp" />
</RelativeLayout>
y para agregar placa:
private void addBadgeToHamburger(int badge){
badge_ham.setVisibility(View.VISIBLE);
String counter = Integer.toString(badge);
String s = " " + counter + " ";
SpannableString sColored = new SpannableString(s);
sColored.setSpan(new RoundedBackgroundSpan(Color.RED, Color.WHITE), s.length() - 3, s.length(), 0);
badge_ham.setText(sColored);
}
Sé que es tarde pero aún así. Si está utilizando el menú de navegación lateral de Android como un iniciador, entonces habrá un nombre de archivo app_bar_main.xml en este archivo. Verá un código como el siguiente, a excepción de TextView. TextView es responsable de mostrar la insignia. Inicialícela en MainActivity . está inicializando su barra de herramientas y cambia su visibilidad de acuerdo con su necesidad (visible cuando el recuento es positivo o no) en este momento, como puede ver, su visibilidad se ha ido

Encontré esta clase de BadgeDrawable realmente genial en Internet y puede agregar un recuento de distintivos a cualquier dibujo que use esta clase. Por favor, siga los pasos a continuación.
Paso 1: agrega primero la clase debajo de tu proyecto.
import android.content.Context;
import android.content.res.Resources;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.ColorFilter;
import android.graphics.Paint;
import android.graphics.PixelFormat;
import android.graphics.Rect;
import android.graphics.Typeface;
import android.graphics.drawable.Drawable;
import android.util.TypedValue;
/**
* Created by Admin on 2/25/2016.
*/
public class BadgeDrawable extends Drawable {
private float mTextSize;
private Paint mBadgePaint;
private Paint mBadgePaint1;
private Paint mTextPaint;
private Rect mTxtRect = new Rect();
private String mCount = "";
private boolean mWillDraw = false;
public BadgeDrawable(Context context) {
mTextSize = dpToPx(context, 8); //text size
mBadgePaint = new Paint();
mBadgePaint.setColor(Color.RED);
mBadgePaint.setAntiAlias(true);
mBadgePaint.setStyle(Paint.Style.FILL);
mBadgePaint1 = new Paint();
mBadgePaint1.setColor(Color.parseColor("#EEEEEE"));
mBadgePaint1.setAntiAlias(true);
mBadgePaint1.setStyle(Paint.Style.FILL);
mTextPaint = new Paint();
mTextPaint.setColor(Color.WHITE);
mTextPaint.setTypeface(Typeface.DEFAULT);
mTextPaint.setTextSize(mTextSize);
mTextPaint.setAntiAlias(true);
mTextPaint.setTextAlign(Paint.Align.CENTER);
}
private float dpToPx(Context context, float value) {
Resources r = context.getResources();
float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, value, r.getDisplayMetrics());
return px;
}
@Override
public void draw(Canvas canvas) {
if (!mWillDraw) {
return;
}
Rect bounds = getBounds();
float width = bounds.right - bounds.left;
float height = bounds.bottom - bounds.top;
// Position the badge in the top-right quadrant of the icon.
/*Using Math.max rather than Math.min */
// float radius = ((Math.max(width, height) / 2)) / 2;
float radius = width * 0.15f;
float centerX = (width - radius - 1) +10;
float centerY = radius -5;
if(mCount.length() <= 2){
// Draw badge circle.
canvas.drawCircle(centerX, centerY, radius+9, mBadgePaint1);
canvas.drawCircle(centerX, centerY, radius+7, mBadgePaint);
}
else{
canvas.drawCircle(centerX, centerY, radius+10, mBadgePaint1);
canvas.drawCircle(centerX, centerY, radius+8, mBadgePaint);
}
// Draw badge count text inside the circle.
mTextPaint.getTextBounds(mCount, 0, mCount.length(), mTxtRect);
float textHeight = mTxtRect.bottom - mTxtRect.top;
float textY = centerY + (textHeight / 2f);
if(mCount.length() > 2)
canvas.drawText("99+", centerX, textY, mTextPaint);
else
canvas.drawText(mCount, centerX, textY, mTextPaint);
}
/*
Sets the count (i.e notifications) to display.
*/
public void setCount(String count) {
mCount = count;
// Only draw a badge if there are notifications.
mWillDraw = !count.equalsIgnoreCase("0");
invalidateSelf();
}
@Override
public void setAlpha(int alpha) {
// do nothing
}
@Override
public void setColorFilter(ColorFilter cf) {
// do nothing
}
@Override
public int getOpacity() {
return PixelFormat.UNKNOWN;
}
}
Paso 2: ahora crea un dibujable (en mi caso es ic_badge_drawable.xml). Luego copia y pega debajo del texto XML.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/ic_main_icon"
android:drawable="@drawable/ic_burger"
android:gravity="center" />
<!-- set a place holder Drawable so android:drawable isn''t null -->
<item android:id="@+id/ic_badge"
android:drawable="@drawable/ic_burger" />
</layer-list>
Aquí puedes pasar cualquier dibujo por ahora, luego podemos pasar cualquier dibujo a esos. Estos son como los titulares de lugar.
Paso 3: Ya hemos configurado todo. Ahora puede usar el método a continuación para establecer el recuento de distintivos para cualquier empate.
private Drawable setBadgeCount(Context context, int res, int badgeCount){
LayerDrawable icon = (LayerDrawable) ContextCompat.getDrawable(context, R.drawable.ic_badge_drawable);
Drawable mainIcon = ContextCompat.getDrawable(context, res);
BadgeDrawable badge = new BadgeDrawable(context);
badge.setCount(String.valueOf(badgeCount));
icon.mutate();
icon.setDrawableByLayerId(R.id.ic_badge, badge);
icon.setDrawableByLayerId(R.id.ic_main_icon, mainIcon);
return icon;
}
Paso 4: Lo usé como se muestra a continuación para cambiar mi ícono de hamburguesa predeterminado.
setSupportActionBar(toolbar);
getSupportActionBar().setHomeAsUpIndicator(setBadgeCount(this,R.drawable.ic_burger, 3));
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowCustomEnabled(true); // enable overriding the default toolbar layout
getSupportActionBar().setDisplayShowTitleEnabled(false);// disable the default title element here (for centered title)
