(ActionMenu)W/InputEventReceiver: 试图完成输入事件，但输入事件接收器已被释放

Question

我制作了操作栏菜单应用程序。但是，如果我单击菜单项，则不会显示吐司消息。我运行模拟器和我的 phone。但它不起作用。当我单击菜单项时，logcat 显示错误消息：

W/InputEventReceiver: Attempted to finish an input event but the input event receiver has already been disposed.

这是我的代码：

MainActivity.java

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.mymenu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.info:
            Toast.makeText(this,"짠",Toast.LENGTH_SHORT);
            return true;
        case R.id.support:
            return true;
        default:
            return  super.onOptionsItemSelected(item);
    }
  }
}

res/menu/mymenu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:id="@+id/help"
    android:title="help"/>
<item
    android:id="@+id/support"
    android:title="support"/>
</menu>

你 Toast.makeText(this,"짠",Toast.LENGTH_SHORT); 应该 Toast.makeText(this,"짠",Toast.LENGTH_SHORT).show(); 调用 show() method.Hope 帮助你。
