Question

我已经实现了导航抽屉，看起来它延伸了大约80％的屏幕。

根据我显示的内容，它在手机上看起来延伸距离太小，在10英寸平板电脑上看起来太多了。

是否可以自定义导航抽屉延伸的距离？

可以通过设置抽屉的layout_width

以编程方式更改抽屉扩展距离

注意：默认情况下，如果layout_width设置为match_parent，那么您将在屏幕上获得80％扩展名的默认行为。

示例代码显示如何以编程方式调整抽屉扩展距离

XML布局中的

：

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

    <!-- MAIN CONTENT -->
    <FrameLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:baselineAligned="false" >

        <!-- STUFF GOES IN HERE FOR YOUR MAIN UI -->

    </FrameLayout>


    <!-- Drawer with black background that pulls out to left: see layout_gravity to change direction -->
    <LinearLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="right"
        android:background="#000000">

        <!-- STUFF GOES IN HERE FOR YOUR DRAWER UI -->

    </LinearLayout>

</android.support.v4.widget.DrawerLayout>

在您的活动中：

// class members
private LinearLayout mDrawer;

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layoutwithdrawer);

    mDrawer = (LinearLayout) findViewById(R.id.drawer_layout);

    // dynamically adjust the layout width so that the drawer extends more or less (code below uses 95%)
    DisplayMetrics displaymetrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
    int width = displaymetrics.widthPixels;
    DrawerLayout.LayoutParams params = (DrawerLayout.LayoutParams) mDrawer.getLayoutParams();
    params.width = (int) (width * 0.95f);
    mDrawer.setLayoutParams(params);
}
