Android对EditTex的图片实现监听

final EditText editText = (EditText) findViewById(R.id.zsm);    editText.setOnTouchListener(new OnTouchListener() {      final int DRAWABLE_LEFT = 0;      final int DRAWABLE_TOP = 1;      final int DRAWABLE_RIGHT = 2;      final int DRAWABLE_BOTTOM = 3;      @Override      public boolean onTouch(View v, MotionEvent event) {        if (event.getX() >= (editText.getRight() - editText            .getCompoundDrawables()[DRAWABLE_RIGHT].getBounds()            .width())){          Toast.makeText(getApplicationContext(), "aaaa", 1000).show();        }          return false;      }    });

private TextWatcher watcher = new TextWatcher(){ @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { Log.d("TAG","[TextWatcher][onTextChanged]"+s); } };

EditText et = (EditText)findViewById(R.id.edit);et.addTextChangedListener(watcher);
