android:基本 Activity 上的按钮点击事件

Question

我为我的应用程序中的所有 Activity 和滑动菜单创建了一个相同布局的 BaseActivity，我在基本 Activity 布局中有一个按钮，我的问题是当我点击按钮时没有任何事情发生并且日志中显示此消息:

D/VelocityTracker﹕ Couldn't open '/dev/touch' (Permission denied)
D/VelocityTracker﹕ tpd read x fail: Bad file number
D/VelocityTracker﹕ tpd read y fail: Bad file number
D/VelocityTracker﹕ Couldn't open '/dev/touch' (Permission denied)

这是我的基本 Activity 布局:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <!-- Put what you want as your normal screen in here, you can also choose for a linear layout or any other layout, whatever you prefer -->
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#FFFFFF"
        android:id="@+id/sub_layout"
       >
        <Button
            android:id="@+id/button_menu"
            style="?android:attr/buttonStyleSmall"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/menu"
            android:text="Ok" />

    </RelativeLayout>
</FrameLayout>
<!-- The navigation drawer -->
<RelativeLayout
    android:id="@+id/left_drawer"
    android:layout_width="250dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp">
</RelativeLayout>

这是我的基本 Activity 代码:

公共(public)类 BaseActivity 扩展 Activity {

protected FrameLayout frameLayout;

protected RelativeLayout mDrawerList;


protected static int position;

private static boolean isLaunch = true;

protected DrawerLayout mDrawerLayout;

private ActionBarDrawerToggle actionBarDrawerToggle;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_base);

    frameLayout = (FrameLayout) findViewById(R.id.content_frame);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (RelativeLayout) findViewById(R.id.left_drawer);



    Button btn_menu = (Button) findViewById(R.id.button_menu);
    btn_menu.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mDrawerLayout.openDrawer(mDrawerList);
            Log.d("Menu is open","???");
        }
    });


}

我不明白这是什么问题。有谁能够帮助我 ？谢谢

Answer 1

你的 xml 有问题..您正在关闭一个不存在的 RelativeLayout..

<FrameLayout>
--- <RelativeLayout>
-------- <Button></Button>
--- </RelativeLayout>
--- </RelativeLayout> *THIS*
</FrameLayout>
