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;
        }
    });

对于任何不想实现可怕的点击处理的人。你可以用RelativeLayout实现同样的效果。有了它,你甚至可以自由处理可绘制对象的定位。

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

   <android.support.design.widget.TextInputLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

     <android.support.design.widget.TextInputEditText
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
      />
     </android.support.design.widget.TextInputLayout>
     <ImageView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_alignParentEnd="true"
       android:layout_centerInParent="true"
       android:src="@drawable/ic_undo"/>
    </RelativeLayout>

ImageView的位置将与你使用drawableEnd相同-加上你不需要所有的触摸监听器处理。只需要点击ImageView的监听器就可以了。

@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);

    }
<FrameLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="5dp" >

            <EditText
                android:id="@+id/edt_status_text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginBottom="10dp"
                android:background="@drawable/txt_box_blank"
                android:ems="10"
                android:hint="@string/statusnote"
                android:paddingLeft="5dp"
                android:paddingRight="10dp"
                android:textColor="@android:color/black" />

            <Button
                android:id="@+id/note_del"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="right"
                android:layout_marginRight="1dp"
                android:layout_marginTop="5dp"
                android:background="@android:drawable/ic_delete" />
        </FrameLayout>

这对我很有用,

mEditTextSearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(s.length()>0){
                mEditTextSearch.setCompoundDrawablesWithIntrinsicBounds(null, null, getResources().getDrawable(android.R.drawable.ic_delete), null);
            }else{
                mEditTextSearch.setCompoundDrawablesWithIntrinsicBounds(null, null, getResources().getDrawable(R.drawable.abc_ic_search), null);
            }
        }
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }
        @Override
        public void afterTextChanged(Editable s) {
        }
    });
    mEditTextSearch.setOnTouchListener(new OnTouchListener() {
        @SuppressLint("ClickableViewAccessibility")
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(mEditTextSearch.getCompoundDrawables()[2]!=null){
                    if(event.getX() >= (mEditTextSearch.getRight()- mEditTextSearch.getLeft() - mEditTextSearch.getCompoundDrawables()[2].getBounds().width())) {
                        mEditTextSearch.setText("");
                    }
                }
            }
            return false;
        }
    });

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:id="@+id/right_button"
                    android:layout_width="24dp"
                    android:layout_height="24dp"
                    android:layout_centerVertical="true"
                    android:layout_alignParentEnd="true"
                    android:layout_marginEnd="12dp"
                    android:background="@color/clear" />
            </RelativeLayout>
