Android 抽屉效果实现

  SlidingDrawer就是重要的抽屉控件 ，handle是抽屉的拖动按钮，content是抽屉中的内容。

      然后建立 chouti的activity类：

import android.app.Activity;
import android.content.Intent;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.SlidingDrawer;


public class Chouti extends Activity {
private GridView gv;
private SlidingDrawer sd;
private ImageView iv;
private List<ResolveInfo> apps;


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.slidingdrawer);
loadApps();
gv = (GridView) findViewById(R.id.allApps);
sd = (SlidingDrawer) findViewById(R.id.sliding);
iv = (ImageView) findViewById(R.id.imageViewIcon);
gv.setAdapter(new GridAdapter());
sd.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener()// 开抽屉
{
@Override
public void onDrawerOpened() {
iv.setImageResource(R.drawable.touch_handler);// 响应开抽屉事件
// ，把图片设为向下的
}
});
sd.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {
@Override
public void onDrawerClosed() {
iv.setImageResource(R.drawable.touch_handler);// 响应关抽屉事件
}
});
}


private void loadApps() {
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);


apps = getPackageManager().queryIntentActivities(intent, 0);
}


public class GridAdapter extends BaseAdapter {
public GridAdapter() {


}


public int getCount() {
// TODO Auto-generated method stub
return apps.size();
}


public Object getItem(int position) {
// TODO Auto-generated method stub
return apps.get(position);
}


public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}


public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ImageView imageView = null;
if (convertView == null) {
imageView = new ImageView(Chouti.this);
imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
imageView.setLayoutParams(new GridView.LayoutParams(50, 50));
} else {
imageView = (ImageView) convertView;
}


ResolveInfo ri = apps.get(position);
imageView.setImageDrawable(ri.activityInfo
.loadIcon(getPackageManager()));


return imageView;
}


}
}
