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?

这是我的简单解决方案,只是把ImageButton放在EditText上:

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

  <EditText android:id="@+id/editTextName"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:imeOptions="actionSearch"
    android:inputType="text"/>

  <ImageButton android:id="@+id/imageViewSearch"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_search"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"/>

</RelativeLayout>

    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;
        }
    });

我想这是一个很好的方法,由Hardik4560推荐,

只需复制粘贴下面的代码,它就能做到这一点。

editMsg.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() >= (editMsg.getRight() - editMsg.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                    // your action here

                    Toast.makeText(ChatActivity.this, "Message Sent", Toast.LENGTH_SHORT).show();
                    return true;
                }
            }
            return false;
        }
    });

//单击右图标

editText.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                final int DRAWABLE_RIGHT = 2;

                if(event.getAction() == MotionEvent.ACTION_UP) {
                    if(event.getRawX() >= (createEventBinding.etAddressLine1.getRight() - createEventBinding.etAddressLine1.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                        // your action here

                        Toast.makeText(getActivity(), "Right icon click", Toast.LENGTH_SHORT).show();

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