如何在警報對話框上顯示ShowCase（Android）

Question

我使用了庫com.github.mreram: showcaseview: 1.1 。

當我想在警報上顯示展示櫃時，它會在警報后面顯示展示櫃。

我幾乎使用了所有ShowCases，但是它們都有相同的問題。

private GuideView ShowCaseView;
private GuideView.Builder ShowCaseBuilder;
private Alert Alert;

@oClick(R.id.bTest)
public void onClick() {
    Alert = new Alert(this);
    Alert.ShowAlert();

    ImageView imgCancel = ButterKnife.findById(Alert, R.id.imgAlertTitle);

    ShowCaseBuilder = new GuideView.Builder(this)
                            .setTitle("Test")
                            .setContentText("Test")
                            .setTargetView(imgCancel)
                            .setContentTypeFace(AppController.Iran)
                            .setTitleTypeFace(AppController.IranBold)
                            .setDismissType(DismissType.anywhere)
                            .setGuideListener(new GuideListener() {
                                @Override
                                public void onDismiss(View view) {
                                    return;
                                }
                            });

      ShowCaseView = ShowCaseBuilder.build();
      if (!ShowCaseView.isShowing())
           ShowCaseView.show();
}

結果看起來像這樣 在這里輸入圖像描述

您需要首先創建自己的自定義Dialor Alert。 然后在其中包含展示代碼。 如何制作CustomDialogAlert的示例：

https://abhiandroid.com/ui/custom-alert-dialog-example-android-studio.html

如何在android中創建自定義對話框？

或嘗試制作類似的課程：

 public class ViewDialog {

    public void showDialog(Activity activity, String msg){
        final Dialog dialog = new Dialog(activity);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);
        dialog.setContentView(R.layout.custom_dialogbox_otp);
        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

        TextView text = (TextView) dialog.findViewById(R.id.txt_file_path);
        text.setText(msg);

        Button dialogBtn_cancel = (Button) dialog.findViewById(R.id.btn_cancel);
        dialogBtn_cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });

        Button dialogBtn_okay = (Button) dialog.findViewById(R.id.btn_okay);
        dialogBtn_okay.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.cancel();
            }
        });
        ShowCaseBuilder = new GuideView.Builder(this)
                        .setTitle("Test")
                        .setContentText("Test")
                        .setTargetView(imgCancel)
                        .setContentTypeFace(AppController.Iran)
                        .setTitleTypeFace(AppController.IranBold)
                        .setDismissType(DismissType.anywhere)
                        .setGuideListener(new GuideListener() {
                            @Override
                            public void onDismiss(View view) {
                                return;
                            }
                        });

        MyShowCaseView = ShowCaseBuilder.build();
        if (!ShowCaseView.isShowing())
            ShowCaseView.show();
             dialog.show();
        }
  }

另外，由於@MikeM指出的問題，您需要創建一個類，該類擴展GuideView並覆蓋顯示，以便在show（）中將視圖添加到正確的位置

public void show() {
    this.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.MATCH_PARENT));
    this.setClickable(false);

    ((ViewGroup) ((Activity) getContext()).getWindow().getDecorView()).addView(this);
    AlphaAnimation startAnimation = new AlphaAnimation(0.0f, 1.0f);
    startAnimation.setDuration(APPEARING_ANIMATION_DURATION);
    startAnimation.setFillAfter(true);
    this.startAnimation(startAnimation);
    mIsShowing = true;
}

我嘗試了完整的MyGuideView：

我做：

    ShowCaseView = new showCaseBuilder.build()
    ShowCaseView.setLayout(parentView)
    if (!ShowCaseView.isShowing())
        ShowCaseView.show()
