ANDROID：简单导航不起作用

时间：2015-03-14 18:42:49

标签： java android navigation up-navigation

Android中的向上导航无效。我想要它做的就是回去。但是每次我点击后退按钮都会关闭应用程序。我跟着android开发者。我的错误日志甚至没有说anthing有用，所以我不知道为什么会这样。我的第一个主要视图是谷歌地图活动，我的第二个视图是一个空白活动，其上面有一个列表视图。

这是我的错误日志

  }

这是我的清单

 <activity
        android:name=".SilentGeofence"
        android:label="@string/title_activity_silent_geofence"
        android:parentActivityName=".AddressList" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".AddressList" />

    </activity>

答案 0 :(得分：1)

    Button button2 = (Button) findViewById(R.id.button2); button2.setOnClickListener(new View.OnClickListener() { public void onClick(View v ) { Intent intent = new Intent(MapsActivity.this, AddressList.class); startActivity(intent);} }); }

删除完成并且它将起作用

如果您只想点击操作栏主页按钮然后返回，请将case android.R.id.home:中的代码替换为：

super.onBackPressed();
break;

这将重新创建后退按钮。
