java - Android警报对话框和设置积极按钮

Question

这是一个滑块拼图。当拼图完成时，我想显示一个带有确定按钮的对话框。当按下 OK 按钮时，我使用一个Intent通过 Android 浏览器加载网站。唯一的问题是，使用当前代码，当拼图完成时，它不会加载一个框（当我使用时它会加载null）。它什么也没做。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);
     }
});

AlertDialog.Builder builder = new AlertDialog.Builder(your_activity.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);
     }
});

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // TODO Auto-generated method stub

                });
