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()。

按照下面的代码绘制右，左，上，下点击:

edittextview_confirmpassword.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() >= (edittextview_confirmpassword.getRight() - edittextview_confirmpassword.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                // your action here                    edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                return true;
            }
        }else{
            edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

        }
        return false;
    }
});

}

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

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。

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;
        }
    });

@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);

    }
