还有更优雅的方式: 不要在TextInputEditText中使用android:drawableRight或android:drawableEnd。

相反，你可以用:

<com.google.android.material.textfield.TextInputLayout
    ...
    app:endIconMode="custom"
    app:endIconDrawable="@drawable/..."

然后使用endIconOnClickListener:

textInputLayout.setEndIconOnClickListener {
  // Respond to end icon presses
}

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;
        }
    });

上述问题的一个可能的解决方案是使用android的新材质组件TextInputLayout。

<com.google.android.material.textfield.TextInputLayout
                    android:id="@+id/searchInput"
                    style="@style/Widget.App.TextInputLayout"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:hint="@string/search"
                    app:endIconMode="custom"
                    app:endIconContentDescription="Search"
                    app:endIconDrawable="@drawable/ic_search">

                    <EditText
                        android:id="@+id/et_search"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"/>

                </com.google.android.material.textfield.TextInputLayout>

在这里设置TextInputLayout属性endIconMode时，将一个按钮放置在所包含的EditText的末尾。

另外app:endIconMode = "custom"允许自定义图标的点击功能

最后，为了监听结束图标单击，调用外围TextInputLayout组件上的setEndIconClickListener()。

我在Mono中实现了@aristo_sh answer。Droid (Xamarin)因为它是一个委托匿名方法你不能返回true或false你必须取e。event。handled。我还隐藏了点击键盘

editText.Touch += (sender, e) => {
                    e.Handled = false;
                    if (e.Event.Action == MotionEventActions.Up)
                    {
                        if (e.Event.RawX >= (bibEditText.Right - (bibEditText.GetCompoundDrawables()[2]).Bounds.Width()))
                        {
                            SearchRunner();
                            InputMethodManager manager = (InputMethodManager)GetSystemService(InputMethodService);
                            manager.HideSoftInputFromWindow(editText.WindowToken, 0);
                            e.Handled = true;
                        }
                    }
                };

我想这是一个很好的方法，由Hardik4560推荐，

考虑以下几点。这不是最优雅的解决方案，但它是有效的，我刚刚测试过。

Create a customized EditText class CustomEditText.java: import android.content.Context; import android.graphics.Rect; import android.graphics.drawable.Drawable; import android.util.AttributeSet; import android.view.MotionEvent; import android.widget.EditText; public class CustomEditText extends EditText { private Drawable dRight; private Rect rBounds; public CustomEditText(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public CustomEditText(Context context, AttributeSet attrs) { super(context, attrs); } public CustomEditText(Context context) { super(context); } @Override public void setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom) { if(right !=null) { dRight = right; } super.setCompoundDrawables(left, top, right, bottom); } @Override public boolean onTouchEvent(MotionEvent event) { if(event.getAction() == MotionEvent.ACTION_UP && dRight!=null) { rBounds = dRight.getBounds(); final int x = (int)event.getX(); final int y = (int)event.getY(); //System.out.println("x:/y: "+x+"/"+y); //System.out.println("bounds: "+bounds.left+"/"+bounds.right+"/"+bounds.top+"/"+bounds.bottom); //check to make sure the touch event was within the bounds of the drawable if(x>=(this.getRight()-rBounds.width()) && x<=(this.getRight()-this.getPaddingRight()) && y>=this.getPaddingTop() && y<=(this.getHeight()-this.getPaddingBottom())) { //System.out.println("touch"); this.setText(""); event.setAction(MotionEvent.ACTION_CANCEL);//use this to prevent the keyboard from coming up } } return super.onTouchEvent(event); } @Override protected void finalize() throws Throwable { dRight = null; rBounds = null; super.finalize(); } } Change your layout XML to this (where com.example is your actual project package name): <com.example.CustomEditText android:id="@+id/txtsearch" … android:layout_gravity="center_vertical" android:background="@layout/shape" android:hint="Enter place,city,state" android:drawableRight="@drawable/cross" /> Finally, add this (or something similar) to your activity: … CustomEditText et = (CustomEditText) this.findViewById(R.id.txtsearch); …

我可能在计算嵌套drawable的触摸边界时有点出错，但你懂的。

我希望这能有所帮助。
