android - 没有操作栏的抽屉导航，android

Question

我正在尝试实现没有任何操作栏的抽屉导航。 我在主布局的顶部有一个小布局，如下所示

我希望当我单击按钮时，抽屉导航将出现在小(彩色)布局下方。 我尝试过一些例子，但抽屉总是这样显示

但我希望抽屉导航将出现在小布局下方，而不是“从顶部”。 我想要这样的东西:

我怎样才能做到这一点？

我尝试过的示例的 xml 文件:

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

    <!-- The first child in the layout is for the main Activity UI -->

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#ffffffff"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        tools:context=".MainActivity" >

        <RelativeLayout
            android:id="@+id/actionBar"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:layout_alignParentTop="true"
            android:background="#0f9d58" >
        </RelativeLayout>

        <RelativeLayout
            android:id="@+id/mainContent"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:layout_below="@id/actionBar"
            android:background="#0f9d58" >

            <Button
                android:id="@+id/actionBarButton"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Click" />

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerHorizontal="true"
                android:layout_marginTop="100dp"
                android:gravity="center"
                android:text="Holy Operating Systems, Batdroid!"
                android:textSize="24sp" />

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentBottom="true"
                android:layout_centerHorizontal="true" />
        </RelativeLayout>
    </RelativeLayout>

    <!-- Side navigation drawer UI -->

    <ListView
        android:id="@+id/navList"
        android:layout_width="200dp"
        android:layout_height="match_parent"
        android:layout_below="@id/actionBar"
        android:layout_gravity="left|start"
        android:background="#ffeeeeee" />

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

主要 Activity 是:

  public class MainActivity extends Activity {

    private ListView mDrawerList;
    private ArrayAdapter<String> mAdapter;
    Button actionBarButton;
    Boolean buttonStateOpen;

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

        buttonStateOpen=false;

        final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout);

        mDrawerList = (ListView)findViewById(R.id.navList);

        addDrawerItems();


        actionBarButton=(Button) findViewById(R.id.actionBarButton);       
        actionBarButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                if(buttonStateOpen==false)
                 {
                    drawer.openDrawer(Gravity.LEFT);
                    buttonStateOpen=true;
                 }
                else if(buttonStateOpen==true)
                {
                    drawer.closeDrawer(Gravity.LEFT);
                    buttonStateOpen=false;
                }
            }
        });


        mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                // TODO Auto-generated method stub
                 Toast.makeText(MainActivity.this, "Time for an upgrade!", Toast.LENGTH_SHORT).show();
            }
        });
    }

    private void addDrawerItems() {
        String[] osArray = { "Android", "iOS", "Windows", "OS X", "Linux" };
        mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, osArray);
        mDrawerList.setAdapter(mAdapter);
    }



}

Answer 1

Approach 1

如果您的布局的高度是固定的，您可以设置从顶部到 ListView 的边距。

Approach 2

使用此方法计算 RelativeLayout 的高度

然后

ViewTreeObserver viewTreeObserver = view.getViewTreeObserver();
if (viewTreeObserver.isAlive()) {
 viewTreeObserver.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
  view.getViewTreeObserver().removeGlobalOnLayoutListener(this);
  viewWidth = view.getWidth();
  viewHeight = view.getHeight();
}
 });
}

然后用它来将运行时边距设置为从顶部开始的 ListView

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
lp.setMargins(left, top, right, bottom);
imageView.setLayoutParams(lp);
