我已经在EditText小部件中添加了文本右侧的图像,使用以下XML:

<EditText
  android:id="@+id/txtsearch"
  ...
  android:layout_gravity="center_vertical"
  android:background="@layout/shape"
  android:hint="Enter place,city,state"
  android:drawableRight="@drawable/cross" />

但我想在单击嵌入图像时清除EditText。我该怎么做呢?

    final TextView mTvTitle = (TextView)findViewById(R.id.tvTitle1);

    mTvTitle.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            final int DRAWABLE_TOP = 1;
            final int DRAWABLE_RIGHT = 2;
            final int DRAWABLE_BOTTOM = 3;

            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(event.getRawX() <= (mTvTitle.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width()))  {
                    // your action here
                    Intent intent = new Intent(DeAddExpences.this,DeHomeActivity.class);
                    startActivity(intent);
                    return true;
                }
            }
            return true;
        }
    });

我已经在Kotlin中实现

edPassword.setOnTouchListener { _, event ->
            val DRAWABLE_RIGHT = 2
            val DRAWABLE_LEFT = 0
            val DRAWABLE_TOP = 1
            val DRAWABLE_BOTTOM = 3
            if (event.action == MotionEvent.ACTION_UP) {
                if (event.rawX >= (edPassword.right - edPassword.compoundDrawables[DRAWABLE_RIGHT].bounds.width())) {
                    edPassword.setText("")
                    true
                }
            }
            false
        }

之前的解决方案在Xamarin Android中都不适用。我能够得到正确的绘制点击监听器工作使用以下:

创建以下OnEditTextTouch事件监听器:

  private void OnEditTextTouch(object sender, View.TouchEventArgs e)
    {
        var rightDrawable = _autoCompleteTextViewSearch.GetCompoundDrawables()[2];

        if (rightDrawable == null || e.Event.Action != MotionEventActions.Up)
        {
            e.Handled = false;

            return;
        }

        if (e.Event.GetX() >= _autoCompleteTextViewSearch.Width - _autoCompleteTextViewSearch.TotalPaddingRight)
        {
            // Invoke your desired action here.

            e.Handled = true;
        }

        // Forward the event along to the sender (crucial for default behaviour)
        (sender as AutoCompleteTextView)?.OnTouchEvent(e.Event);
    }

订阅Touch事件:

_autoCompleteTextViewSearch.Touch += OnEditTextTouch;
@Override
    public boolean onTouch(View v, MotionEvent event) {

        Drawable drawableObj = getResources().getDrawable(R.drawable.search_btn);
        int drawableWidth = drawableObj.getIntrinsicWidth();

        int x = (int) event.getX();
        int y = (int) event.getY();

        if (event != null && event.getAction() == MotionEvent.ACTION_UP) {
            if (x >= (searchPanel_search.getWidth() - drawableWidth - searchPanel_search.getPaddingRight())
                    && x <= (searchPanel_search.getWidth() - searchPanel_search.getPaddingRight())

                    && y >= searchPanel_search.getPaddingTop() && y <= (searchPanel_search.getHeight() - searchPanel_search.getPaddingBottom())) {

                getSearchData();
            }

            else {
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.showSoftInput(searchPanel_search, InputMethodManager.SHOW_FORCED);
            }
        }
        return super.onTouchEvent(event);

    }

实际上,您不需要扩展任何类。假设我有一个EditText editComment和一个drawableRight

editComment.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        final int DRAWABLE_LEFT = 0;
        final int DRAWABLE_TOP = 1;
        final int DRAWABLE_RIGHT = 2;
        final int DRAWABLE_BOTTOM = 3;

        if(event.getAction() == MotionEvent.ACTION_UP) {
            if(event.getRawX() >= (editComment.getRight() - editComment.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                // your action here

                return true;
            }
        }
        return false;
    }
});

我们getRawX(),因为我们想要得到实际的触摸在屏幕上的位置,而不是相对于父。

要获得左侧点击

if(event.getRawX() <= (editComment.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width())) 

我是这样做的

            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

                <android.support.design.widget.TextInputLayout
                    android:id="@+id/til_text"

                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_alignParentTop="true"
                    android:textColorHint="@color/colorSilver">

                    <android.support.design.widget.TextInputEditText
                        android:id="@+id/tiet_text"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:gravity="top|left"
                        android:hint="@string/rep_hint"
                        android:inputType="textMultiLine"
                        android:maxLines="3"
                        android:drawableEnd="@drawable/ic_attach_photo"
                        android:drawablePadding="5dp"
                        android:textColor="@color/colorPrimaryText"
                        android:textColorHint="@color/colorSilver"
                      />

                </android.support.design.widget.TextInputLayout>

                <View

                    android:layout_alignParentEnd="true"
                    android:layout_marginEnd="12dp"
                    android:background="@color/clear" />
            </RelativeLayout>
