将活动显示为对话框[重复]

Question

这是我想成为对话的活动：

public class TrainerBookingDialogActivity extends AppCompatActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_trainer_booking_dialog);

    }



  <activity android:name="com.clearmindai.trainer.module.bookdialog.TrainerBookingDialogActivity"
            android:theme="@android:style/Theme.Holo.Light.Dialog"></activity>

我这样称呼它：

  public static  void showBookedDialog(Context context) {
        Intent intent=new Intent(getApplicationContext(), TrainerBookingDialogActivity.class);
        context.startActivity(intent);
        //show dialog
    }

但错误告诉我：

您需要使用 Theme.AppCompat 主题（或后代） 活动。

Answer 1

试试这个代码

public class MyCustomDialogFragment extends DialogFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
 }
 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle s 
 avedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_my_custom_dialog, container, false); 
   // Do all the stuff to initialize your custom view

    return v;
} 
}
