次のコードを実行すると、例外が発生します。処理が完了し、プログレスバーが 100% に達すると、このファイル ダイアログが表示されます。FileSaveDialog は Dialog を拡張し、OnCompletionListener を実装します
runOnUiThread(new Runnable() {
@Override
public void run() {
showDialog(error.Code());//Line 557
}
});
@Override
protected Dialog onCreateDialog(int id) {
Dialog dialog;
AlertDialog.Builder builder;
final ScrollView scrollView = new ScrollView(this);
final TextView textView = new TextView(this);
switch (id) {
// Other cases are here
case 4:
File playFile = new File(mediaPath, TEMP_WAV_FILE_NAME);
dialog = new FileSaveDialog(this, getResources(),
playFile.getAbsolutePath(), saveDiscardHandler);
dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
// do whatever you want the back key to do
cleanUp();
}
});
break;
// Other cases are here
default:
dialog = null;
}
return dialog;
}
