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?


当前回答

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>

其他回答

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;
        }
    });

这么多的解决方案,但没有一个适合我,当我有两个连续的领域。 这是添加清除按钮编辑文本的解决方案,在我有两个字段或一行中的一个字段的情况下为我工作。用kotlin写的!

@SuppressLint("PrivateResource")
fun <T : EditText> T.withClear(): T {
    addTextChangedListener(object : TextWatcher {
        override fun afterTextChanged(editable: Editable) {
            setCompoundDrawablesWithIntrinsicBounds(0, 0,
                    if (editable.isNotEmpty()) abc_ic_clear_material else 0, 0)
        }

        override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) = Unit
        override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) = Unit
    })

    setOnTouchListener { _, event ->
        if (event.action == ACTION_UP && event.x >= (right - this.compoundPaddingRight)) {
            setText("")
            return@setOnTouchListener true
        }
        false
    }
    return this
}
@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>

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;
        }
    });
