[英]Android Sliding Drawer Open On Create
I want to have a slider that is open when the app starts. 我想要一个在应用启动时打开的滑块。 It will be open with buttons and such and when the user closes it, there will be more buttons to access. 它将通过按钮等打开,当用户关闭它时,将有更多按钮可供访问。 Is this possible with a sliding drawer? 滑动抽屉可以吗? What would I add to the onCreate() method? 我会在onCreate()方法中添加什么?
Thanks 谢谢
XML Layout - In a basic LinearLayout: XML布局-在基本的LinearLayout中:
<SlidingDrawer
android:id="@+id/slide"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:content="@+id/content"
android:handle="@+id/handle"
android:orientation="vertical"
android:scrollbars="vertical" >
<LinearLayout
android:id="@id/handle"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/btn"
android:gravity="center"
android:orientation="horizontal" >
<ImageView
android:id="@+id/handleImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_tray_expand" />
<Button
android:id="@+id/handleButton"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@drawable/btn"
android:text="Up me" />
</LinearLayout>
<LinearLayout
android:id="@+id/content"
android:paddingTop="2dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#013E53"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:id="@+id/tv_commentDisplay"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="left"
android:paddingLeft="10dp"
android:textSize="20dp" />
</LinearLayout>
</SlidingDrawer>
And your Activity will looks like this: 您的活动将如下所示:
public class Home extends Activity implements OnDrawerScrollListener
{
private ImageView handleImage;
private Button handleButton;
private SlidingDrawer slide;
private TextView tv_commentDisplay;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
tv_commentDisplay = (TextView)this.findViewById(R.id.tv_commentDisplay);
handleImage = (ImageView)this.findViewById(R.id.handleImage);
handleButton = (Button)this.findViewById(R.id.handleButton);
slide = (SlidingDrawer)this.findViewById(R.id.slide);
slide.open(); // not sure
slide.setOnDrawerScrollListener(this);
handleButton = ((Button)this.findViewById(R.id.handleButton));
tv_commentDisplay.setText("Hello World");
}
@Override
public void onScrollEnded() {
}
@Override
public void onScrollStarted() {
if (slide.isOpened())
handleImage.setImageResource(R.drawable.ic_tray_collapse);
else {
handleImage.setImageResource(R.drawable.ic_tray_expand);
}
}
