Android alert dialog and set positive button
提问by user1287230
This is for a slider puzzle. I want to show a dialog box with OK button when the puzzle is completed. When the OK button is pressed, I use an Intentto load a website via Android browser. Only problem is that with the current code, when the puzzle is complete, it does not load a box (it does when I use null). It doesn't do anything. Any ideas?
这是一个滑块拼图。我想在拼图完成后显示一个带有 OK 按钮的对话框。当按下 OK 按钮时，我使用 anIntent通过 Android 浏览器加载网站。唯一的问题是，对于当前的代码，当拼图完成时，它不会加载一个盒子（当我使用 时会加载null）。它什么也不做。有任何想法吗？
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(!puzzle.isSolved() ? R.string.title_stats : stats.isNewBest() ? R.string.title_new_record : R.string.title_solved);
builder.setMessage(msg);
builder.setPositiveButton(R.string.label_ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent("android.intent.action.VIEW", Uri.parse("http://www..com"));
Bundle b = new Bundle();
b.putBoolean("new_window", true); //sets new window
intent.putExtras(b);
startActivity(intent);
}
});
