manager - evento de pasta android

on paste event

Question

¿Hay alguna manera de atrapar el evento de pegar en mi aplicación? Debo hacer algo cuando hago clic largo en un texto de edición y selecciono Pegar en el menú contextual. Gracias

Answer 1

Crear menu.xml con la posición ''pegar''

Registre contextMenu en su EditText

EditText et=(EditText)findViewById(R.id.et);
registerForContextMenu(et);

Crear contextMenu

@Override
public void onCreateContextMenu(ContextMenu menu, View v,
        ContextMenuInfo menuInfo) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);    
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) menuInfo;  
    menu.setHeaderTitle("title");
}

Crear menú de método onClick

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterContextMenuInfo info = (AdapterContextMenuInfo)item.getMenuInfo();     
    switch (item.getItemId()) {
    case R.id.paste:      
        break;     
    }
    return true;
}

Answer 2

A continuación se muestra un código donde puede anular la barra de acciones copiar / Pegar, etc.

public class MainActivity extends Activity {
    EditText editText;
    private ClipboardManager myClipboard;
    private ClipData myClip;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        myClipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
        editText = (EditText) findViewById(R.id.editText3);

        myClipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
        editText = (EditText) findViewById(R.id.editText3);
        editText.setCustomSelectionActionModeCallback(new Callback() {

            @Override
            public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
                // TODO Auto-generated method stub
                return false;
            }

            @Override
            public void onDestroyActionMode(ActionMode mode) {
                // TODO Auto-generated method stub

            }

            @Override
            public boolean onCreateActionMode(ActionMode mode, Menu menu) {
                // TODO Auto-generated method stub
                return true;
            }

            @Override
            public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
                // TODO Auto-generated method stub
                switch (item.getItemId()) {
                case android.R.id.copy:
                    int min = 0;
                    int max = editText.getText().length();
                    if (editText.isFocused()) {
                        final int selStart = editText.getSelectionStart();
                        final int selEnd = editText.getSelectionEnd();

                        min = Math.max(0, Math.min(selStart, selEnd));
                        max = Math.max(0, Math.max(selStart, selEnd));
                    }
                    // Perform your definition lookup with the selected text
                    final CharSequence selectedText = editText.getText()
                            .subSequence(min, max);
                    String text = selectedText.toString();

                    myClip = ClipData.newPlainText("text", text);
                    myClipboard.setPrimaryClip(myClip);
                    Toast.makeText(getApplicationContext(), "Text Copied",
                            Toast.LENGTH_SHORT).show();
                    // Finish and close the ActionMode
                    mode.finish();
                    return true;
                case android.R.id.cut:
                    // add your custom code to get cut functionality according
                    // to your requirement
                    return true;
                case android.R.id.paste:
                    // add your custom code to get paste functionality according
                    // to your requirement
                    return true;

                default:
                    break;
                }
                return false;
            }
        });         
    }    
}

Answer 3

Debería implementar un escucha de TextWatcher en el control que recibe la acción pegar.

La clase TextWatcher proporciona métodos para manejar OnChange, BeforeChange y AfterChange de cualquier Editable. Por ejemplo:

private void pasteEventHandler() {
    ((EditText)findViewById(R.id.txtOutput))
            .addTextChangedListener(new TextWatcher() {

                public void afterTextChanged(Editable s) {
                    Log.d(TAG, "Text changed, refreshing view.");
                    refreshView();
                }

                public void beforeTextChanged(CharSequence s, int start,
                        int count, int after) {
                }

                public void onTextChanged(CharSequence s, int start,
                        int before, int count) {
                }
            });
}

Answer 4

Puede configurar la clase de escucha:

public interface GoEditTextListener {
void onUpdate();

}

Сreate self class para EditText:

public class GoEditText extends EditText
{
    ArrayList<GoEditTextListener> listeners;

    public GoEditText(Context context)
    {
        super(context);
        listeners = new ArrayList<>();
    }

    public GoEditText(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        listeners = new ArrayList<>();
    }

    public GoEditText(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
        listeners = new ArrayList<>();
    }

    public void addListener(GoEditTextListener listener) {
        try {
            listeners.add(listener);
        } catch (NullPointerException e) {
            e.printStackTrace();
        }
    }

    /**
     * Here you can catch paste, copy and cut events
     */
    @Override
    public boolean onTextContextMenuItem(int id) {
        boolean consumed = super.onTextContextMenuItem(id);
        switch (id){
            case android.R.id.cut:
                onTextCut();
                break;
            case android.R.id.paste:
                onTextPaste();
                break;
            case android.R.id.copy:
                onTextCopy();
        }
        return consumed;
    }

    public void onTextCut(){
    }

    public void onTextCopy(){
    }

    /**
     * adding listener for Paste for example
     */
    public void onTextPaste(){
        for (GoEditTextListener listener : listeners) {
            listener.onUpdate();
        }
    }
}

xml:

<com.yourname.project.GoEditText
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/editText1"/>

Y en tu actividad:

private GoEditText editText1;

editText1 = (GoEditText) findViewById(R.id.editText1);

            editText1.addListener(new GoEditTextListener() {
                @Override
                public void onUpdate() {
//here do what you want when text Pasted
                }
            });
