Question

如何在DrawerLayout中更改LinearLayout的参数？

我试过了：

LinearLayout linearLayout;

在onCreate之后

：

    drawerLinearLayout = (LinearLayout)findViewById(R.id.drawer);

// drawer is the id of the linearlayout, where I want to change its params

DrawerLayout.LayoutParams lp = new DrawerLayout.LayoutParams(100,100);
linearLayout.setLayoutParams(lp);

xml就像：

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

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical"
                tools:context=".Main" />

            <LinearLayout
                android:id="@+id/drawer"
                android:layout_width="240dp"
                android:layout_height="match_parent"
                android:orientation="vertical">

    <ListView
android:id="@+id/list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
/>
    </LinearLayout>

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

没有错误，但抽屉的尺寸不是100 x 100 - 它需要整个宽度和高度：S

编辑：

    public class MainActivity extends FragmentActivity {

    LinearLayout drawerLinearLayout;




    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        setContentView(R.layout.main);
    drawerLinearLayout = (LinearLayout)findViewById(R.id.drawer);

        int mode = getResources().getConfiguration().orientation;

        if (mode == 1) {

DrawerLayout.LayoutParams lp = new DrawerLayout.LayoutParams(2,2);
drawerLinearLayout.setLayoutParams(lp);

        } 


}}
