我已经安装了所有应用程序,并且拥有一个列表视图。我需要onItemLongClick
卸载我在列表视图中单击的应用程序。 onItemLongClick的起始代码是这样的:
@Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
return false;
}
这是用于卸载:
ApplicationInfo app = applist.get(position);
Uri packageUri = Uri.parse("package:"+app.packageName);
Intent uninstallIntent =
new Intent(Intent.ACTION_DELETE, packageUri);
startActivity(uninstallIntent);
return true;
我还需要插入一些参数,并尝试使用此参数,但是在
onItemLongClick
中出现错误:protected boolean setOnItemLongClickListener(ListView l, View v, int position, long id) {
super.onItemLongClick(l, v, position, id);// Error
ApplicationInfo app = applist.get(position);
Uri packageUri = Uri.parse("package:"+app.packageName);
Intent uninstallIntent =
new Intent(Intent.ACTION_DELETE, packageUri);
startActivity(uninstallIntent);
return true;
}
我该如何解决?
最佳答案
尝试实现这个
import android.widget.AdapterView.OnItemLongClickListener;
yourListView.setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "delete item in position : " + arg2, Toast.LENGTH_SHORT).show();
return false;
}
});
关于java - Listview和onItemLongClick不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/19618446/
