我创建了一个简单的自定义触摸侦听器类，而不是自定义EditText

public class MyTouchListener implements View.OnTouchListener {
private EditText editText;

public MyTouchListener(EditText editText) {
    this.editText = editText;

    setupDrawable(this.editText);
}

private void setupDrawable(final EditText editText) {
    editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(s.length()>0)
                editText.setCompoundDrawablesWithIntrinsicBounds(0,0, R.drawable.clearicon,0);
            else
                editText.setCompoundDrawablesWithIntrinsicBounds(0,0, 0,0);

        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });
}

@Override
public boolean onTouch(View v, MotionEvent event) {
    if(event.getAction() == MotionEvent.ACTION_UP) {
        if(editText.getCompoundDrawables()[2]!=null){
            if(event.getX() >= (editText.getRight()- editText.getLeft() - editText.getCompoundDrawables()[2].getBounds().width())) {
                editText.setText("");
            }
        }
    }
    return false;

}

}

当EditText为空白时，将没有可绘制对象。绘图将显示我们开始编辑以清除EditText的时间。

你可以设置触摸监听器

mEditText.setOnTouchListener（new MyTouchListener（mEditText））;

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;
        }
    });

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
}

我见过几个解决方案，但没有一个能说服我。要么非常复杂，要么太简单(不可重用)。

这是我目前最喜欢的方法:

mEditText.setOnTouchListener(
        new OnEditTextRightDrawableTouchListener(mEditText) {
          @Override
          public void OnDrawableClick() {
            // The right drawable was clicked. Your action goes here.
          }
        });

这是可重复使用的触摸监听器:

import android.graphics.drawable.Drawable;
import android.support.annotation.NonNull;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.EditText;

public abstract class OnEditTextRightDrawableTouchListener implements OnTouchListener {

  private final EditText mEditText;

  public OnEditTextRightDrawableTouchListener(@NonNull final EditText editText) {
    mEditText = editText;
  }

  @Override
  public boolean onTouch(View view, MotionEvent motionEvent) {
    if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
      final int DRAWABLE_RIGHT_POSITION = 2;
      final Drawable drawable = mEditText.getCompoundDrawables()[DRAWABLE_RIGHT_POSITION];
      if (drawable != null) {
        final float touchEventX = motionEvent.getX();
        final int touchAreaRight = mEditText.getRight();
        final int touchAreaLeft = touchAreaRight - drawable.getBounds().width();
        if (touchEventX >= touchAreaLeft && touchEventX <= touchAreaRight) {
          view.performClick();
          OnDrawableClick();
        }
        return true;
      }
    }
    return false;
  }

  public abstract void OnDrawableClick();
}

你可以在这里看到要点。

这对我有用:)希望这对你也有帮助

edit_account_name.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                if (event.getRawX() >= (edit_account_name.getRight())) {
                    //clicked
                   return true;
                }
            }
            return false;
        }
    });
