滑动抽屉安卓打不开

Question

我在 android 中实现了一个抽屉，当打开时显示 4 个按钮，但是当我尝试单击它时，这实际上从未发生过（抽屉没有打开）。但是，当我单击抽屉时，组件 ImageView 处理程序的图像资源会发生变化。

我有以下 XML 代码：

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/dynamicCategories"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/background"
        android:orientation="vertical" >

        <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="center"
        android:layout_marginTop="10dp"
        android:layout_weight="0.1"
        android:orientation="horizontal" >
             .
             .
             .

        </LinearLayout>

            <LinearLayout
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/LinearLayout01"
                android:layout_width="fill_parent"
                android:layout_height="42dp"
                android:layout_weight="0.1"
                android:gravity="bottom"
                android:orientation="vertical" >

                <SlidingDrawer
                    android:id="@+id/slidingDrawer1"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:background="@drawable/bar"
                    android:content="@+id/contentLayout"
                    android:handle="@+id/handle" >

                    <ImageView
                        android:id="@+id/handle"
                        android:layout_width="fill_parent"
                        android:layout_height="fill_parent"
                        android:layout_weight="1" />

                    <LinearLayout
                        android:id="@+id/contentLayout"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:background="@color/white" >

                        <Button
                            android:id="@+id/button1"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:layout_weight="1"
                            android:text="Button" />

                        <Button
                            android:id="@+id/button2"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:layout_weight="1"
                            android:text="Button" />

                        <Button
                            android:id="@+id/button3"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:layout_weight="1"
                            android:text="Button" />

                        <Button
                            android:id="@+id/button4"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:layout_weight="1"
                            android:text="Button" />
                    </LinearLayout>
                </SlidingDrawer>

            </LinearLayout>

还有java代码：

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

    drawer = (SlidingDrawer) findViewById(com.android.layout.R.id.slidingDrawer1);
        // Drawer Programmation
    drawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {
        public void onDrawerOpened() {
            ImageView view = (ImageView) drawer.getHandle();
            // change to bar selected   
               view.setImageResource(com.android.layout.R.drawable.ic_launcher);
            Toast.makeText(getApplicationContext(), "Is open!", 3000)
                    .show();
            drawer.open();
        }
    });
    drawer.setOnDrawerCloseListener(new OnDrawerCloseListener() {

        public void onDrawerClosed() {
            Toast.makeText(getApplicationContext(), "Closed", 3000).show();
            ImageView view = (ImageView) drawer.getHandle();
            view.setImageResource(0);
            drawer.close();
        }
    });

Answer 1

我发现了问题...我的线性布局具有 42dp 的滑动抽屉。因此，当尝试使用滑动抽屉时，线性布局打开但没有足够的空间展开。

看，伙计，它很容易不要在代码中分配任何东西，简单的布局将非常适合一侧滑动抽屉

检查布局

<?xml version="1.0" encoding="utf-8"?>

 android:layout_width="fill_parent"
 android:layout_height="fill_parent">

      android:layout_gravity="right"
      android:padding="10dp" >
 <TextView
            android:id="@+id/text1"

            android:layout_height="wrap_content"
            android:layout_gravity="center"

       <Button

           android:layout_width="110dp"
           android:layout_height="55dp"
           android:layout_marginLeft="35dp"
           android:layout_marginTop="20dp"
           android:background="@drawable/signup"

       <Button

           android:layout_marginLeft="18dp"

           android:background="@drawable/liginbtn"
            android:text="Sign up"
           android:textColor="#ffffffff"
           android:textSize="20dp" />
   </LinearLayout>

  </LinearLayout>
 </SlidingDrawer>
</FrameLayout>

还有android java代码..

       public class MainActivity extends Activity {
/** Called when the activity is first created. */

     @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.xml);

}
  }
