時，應用程序崩潰我有一個列表視圖，包含從數據庫中填充。我在每一行上放一個按鈕，當它被點擊時，它會顯示一個AlertDialog對話框。當AlertDialog約爲
我的項目沒有錯誤，但每次點擊AlertDialog框的按鈕時，應用程序都會崩潰。
這裏是我的代碼：
donate_now.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
AlertDialog.Builder alertbox = new AlertDialog.Builder(ProjectsList.this);
alertbox.setTitle("SMS");
alertbox.setMessage (Html.fromHtml(("Ihr SMS wird vorbereitet. Bitte
bestätigen Sie mit 'Ok' und senden Sie danach die SMS ab!
<p><small>Sie helfen dem Projekt mit " +mPriceIndex + ".
Betrag je SMS zzgl. Transport. Der Betrag abzüglich 17 Cent
geht direkt an die Partner-Organisation.")));
alertbox.setNeutralButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
Intent sendIntent = new Intent(Intent.ACTION_VIEW);
sendIntent.putExtra("address", mShortcodeIndex);
sendIntent.putExtra("sms_body", mKeywordIndex);
sendIntent.setType("vnd.android-dir/mms-sms");
startActivity(sendIntent);
}
});
alertbox.show();
誰能幫我分析一下我出問題在哪裏？
這裏的調試：

你可以把整個活動代碼。 Beco'z這段代碼可以正常工作，只需按一下按鈕即可。 – user370305
是的，我剛更新了這個問題。請看看，謝謝 – hectichavana
