Android - SlidingPaneLayout - 在 Pane 上设置宽度

Question

我在 Activity 中使用 SlidingPaneLayout:

<android.support.v4.widget.SlidingPaneLayout     xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/myslidingpanelayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

<!-- menu left -->
<LinearLayout
    android:id="@+id/menu"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:background="#8d305f"
    android:orientation="vertical" >
...
</LineareLayout>

<!-- main page right-->
<LinearLayout
    android:id="@+id/right_main"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:background="#fff"
    android:orientation="vertical" >
...
</LineareLayout>
</android.support.v4.widget.SlidingPaneLayout>

我希望菜单覆盖页面的 3/4 我希望它可以在所有手机上使用，所以我不能放例如

android:layout_width="300dp"

我要计算屏幕宽度并设置到左 Pane

谢谢你的帮助

谢谢大家，我找到了这个答案并且对我有用:

    int width;
    int height;
    if (android.os.Build.VERSION.SDK_INT >= 13){
        Display display = getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        width = size.x;
        height = size.y;
    }else {
        Display display = getWindowManager().getDefaultDisplay(); 
        width = display.getWidth();  // deprecated
        height = display.getHeight();  // deprecated
    }
    if(width>0&&height>0){
        LinearLayout layout = (LinearLayout)findViewById(R.id.menu);
        // Gets the layout params that will allow you to resize the layout
        LayoutParams params = layout.getLayoutParams();
        // Changes the height and width to the specified *pixels*
        params.height = height;
        params.width = width*3/4;
    }
