Ich versuche, eine sehr einfache App zu schreiben, die den Namen jeder installierten App auf dem Gerät in einer Listenansicht anzeigt. Ich verwende das ListView-Tutorial von Google als Grundlage.
Hier ist mein Code:
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
final PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
final ArrayList<ResolveInfo> list =
(ArrayList<ResolveInfo>) pm.queryIntentActivities(intent,
PackageManager.PERMISSION_GRANTED);
for (ResolveInfo rInfo : list)
{
Log.i(TAG, ": Installed Applications " + rInfo.activityInfo.
applicationInfo.loadLabel(pm).toString());
}
final ArrayAdapter<ResolveInfo> adapter =
new ArrayAdapter<ResolveInfo>(this, R.layout.list_item, list)
{
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
if (convertView == null)
convertView = LayoutInflater.from(parent.getContext()).
inflate(R.layout.list_item, parent, false);
final String text = list.get(position).activityInfo.
applicationInfo.loadLabel(pm).toString();
((TextView)convertView.findViewById(R.id.text)).setText(text);
final Drawable drawable = list.get(position).activityInfo.applicationInfo.loadIcon(pm);
((ImageView)convertView.findViewById(R.id.image)).setImageDrawable(drawable);
return convertView;
}
};
setListAdapter(adapter);
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// On Item Click Activity
// This is where I want to send the Package Name of the app selected to be passed to a method.
}
});
}
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="@+id/image"
android:layout_width="50dp" android:layout_height="50dp" />
<TextView android:id="@+id/text"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:padding="10dp" android:textSize="16sp" />
</LinearLayout> UPDATE: Ich muss jetzt einen OnItemClickListener verwenden, um den Paketnamen der ausgewählten App an eine Methode zu übergeben.
