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;
                        }
                    }
                };

<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>

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。

使用可扩展的textview缓冲区可能是一个解决方案。看看这个简短而切中要害的教程:首先，点击事件要容易得多

https://android-designing.blogspot.com/2017/01/spannable-textview-with-image-clickable.html?m=1

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
}

Kotlin是一种很棒的语言，每个类都可以使用新方法进行扩展。让我们为EditText类介绍一个新方法，它将捕捉点击到右绘图。

fun EditText.onRightDrawableClicked(onClicked: (view: EditText) -> Unit) {
this.setOnTouchListener { v, event ->
    var hasConsumed = false
    if (v is EditText) {
        if (event.x >= v.width - v.totalPaddingRight) {
            if (event.action == MotionEvent.ACTION_UP) {
                onClicked(this)
            }
            hasConsumed = true
        }
    }
    hasConsumed
}
}

你可以看到它以回调函数作为参数，当用户单击右可绘制时调用。

val username = findViewById<EditText>(R.id.username_text)
    username.onRightDrawableClicked {
        it.text.clear()
    }
