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?

<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>

我认为如果我们使用一些技巧会容易得多:)

用图标创建一个图像按钮,并设置其背景 颜色要透明。 将图像按钮放在EditText和右边 实现按钮的onclick侦听器来执行您的 函数

Done

用于左侧可绘制的单击侦听器

txt.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;

            if (event.getAction() == MotionEvent.ACTION_UP) {
                if (event.getRawX() <= (txt
                        .getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width() +
                        txt.getPaddingLeft() +
                        txt.getLeft())) {

                          //TODO do code here
                    }
                    return true;
                }
            }
            return false;
        }
    });

我已经采取了@AZ_的解决方案,并将其转换为kotlin扩展函数:

所以在代码中复制这个:

@SuppressLint("ClickableViewAccessibility")
fun EditText.setDrawableRightTouch(setClickListener: () -> Unit) {
    this.setOnTouchListener(View.OnTouchListener { _, event ->
        val DRAWABLE_LEFT = 0
        val DRAWABLE_TOP = 1
        val DRAWABLE_RIGHT = 2
        val DRAWABLE_BOTTOM = 3
        if (event.action == MotionEvent.ACTION_UP) {
            if (event.rawX >= this.right - this.compoundDrawables[DRAWABLE_RIGHT].bounds.width()
            ) {
                setClickListener()
                return@OnTouchListener true
            }
        }
        false
    })
}

你可以在EditText上调用setDrawableRightTouch函数来使用它:

yourEditText.setDrawableRightTouch {
    //your code
}

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>

非常非常好,感谢所有参与讨论的人。因此,如果你不想处理扩展类带来的不便,你可以执行以下操作(仅为正确的可绘制对象实现)

this.keyword = (AutoCompleteTextView) findViewById(R.id.search);
this.keyword.setOnTouchListener(new RightDrawableOnTouchListener(keyword) {
        @Override
        public boolean onDrawableTouch(final MotionEvent event) {
            return onClickSearch(keyword,event);
        }
    });

private boolean onClickSearch(final View view, MotionEvent event) {
    // do something
    event.setAction(MotionEvent.ACTION_CANCEL);
    return false;
}

下面是基于@Mark的回答的基本侦听器实现

public abstract class RightDrawableOnTouchListener implements OnTouchListener {
    Drawable drawable;
    private int fuzz = 10;

    /**
     * @param keyword
     */
    public RightDrawableOnTouchListener(TextView view) {
        super();
        final Drawable[] drawables = view.getCompoundDrawables();
        if (drawables != null && drawables.length == 4)
            this.drawable = drawables[2];
    }

    /*
     * (non-Javadoc)
     * 
     * @see android.view.View.OnTouchListener#onTouch(android.view.View, android.view.MotionEvent)
     */
    @Override
    public boolean onTouch(final View v, final MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN && drawable != null) {
            final int x = (int) event.getX();
            final int y = (int) event.getY();
            final Rect bounds = drawable.getBounds();
            if (x >= (v.getRight() - bounds.width() - fuzz) && x <= (v.getRight() - v.getPaddingRight() + fuzz)
                    && y >= (v.getPaddingTop() - fuzz) && y <= (v.getHeight() - v.getPaddingBottom()) + fuzz) {
                return onDrawableTouch(event);
            }
        }
        return false;
    }

    public abstract boolean onDrawableTouch(final MotionEvent event);

}
