ProgressDialog
ユーザーがボタンをクリックしたときに表示する を作成しました。
ちなみに私の活動はTabgroup
これが私のコードですProgressDialog
final ProgressDialog myPd_ring=ProgressDialog.show(MainActivity.this, "Please wait", "Loading please wait..", true);
myPd_ring.setCancelable(false);
new Thread(new Runnable() {
public void run() {
// TODO Auto-generated method stub
try
{
//Some data binding here....
}catch(Exception e){
}
myPd_ring.dismiss();
Intent edit = new Intent(getDialogContext(), MerchantActivity.class);
TabGroupActivity parentsActivity = (TabGroupActivity)getParent();
parentsActivity.startChildActivity("MerchantActivity", edit);
}
}).start();
インテントを使用するまで、すべてが正常に機能するようになりました。エラーが発生します
これが私のLogCatです:
