使用

  这里只介绍java 版使用方法，kotin版使用可以在github的app里面看到（正常使用）：

BottomAlertDialog dialog = new BottomAlertDialog()
                    .openFullScreenMask(false,R.color.color_transparent,0.1f) //是否开启全屏以及弹框透明度，设置true则无法修改dialog位置，仅限底部使用
                    .setBackGroundColor(R.color.white)
                    .setContent("Exiting out of this form will remove all record information. Would you like to exit anyway?")
                    .setConfirmBg(R.drawable.bg_button_full_green_408)
                    .setCancelBg(R.drawable.bg_button_login_full_border_black_stroke_2)
                    .setTitle("Java title")
                     //.setCancelBtnGone() //是否隐藏取消按钮
                    .setTitleColor(R.color.black)
                    .setGravityStyle(Gravity.BOTTOM)
                    .setCanceledOnTouchOutside(false)
                    .setPositiveButtonMethod("Ok",R.color.white,(d,view) ->{
                        d.dismiss();
                        return null;
                    })
                    .setNegativeButtonMethod("Cancel",R.color.black,(d,view) ->{
                        d.dismiss();
                        return null;
                    })
                    .setFragmentManager(getSupportFragmentManager())
                    ;
            dialog.show();

 BottomChoiceDialog bottomChoiceDialog = new BottomChoiceDialog(
                    arrayList,(position,value) ->{
                        switch (position){
                            case 0 :
                                Toast.makeText(this, "take photo", Toast.LENGTH_SHORT).show();
                                break;
                            case 1 :
                                Toast.makeText(this, "Select from library", Toast.LENGTH_SHORT).show();
                                break;
                            case 2 :
                                Toast.makeText(this, "View image full Screen", Toast.LENGTH_SHORT).show();
                                break;
                        }
                return null;
            });
            bottomChoiceDialog.show(getSupportFragmentManager(),"dialog");

中间圆角样式

 BottomAlertDialog dialog = new BottomAlertDialog()
                    .openFullScreenMask(false, R.color.color_transparent,0.1f)
                    .setBackGroundColor(R.drawable.bg_dialog_full_radius_14_white)
                    .setContent("Exiting out of this form will remove all record information. Would you like to exit anyway?")
                    .setConfirmBg(R.drawable.bg_button_full_green_408)
                    .setCancelBg(R.drawable.bg_button_login_full_border_black_stroke_2)
                    .setTitle("Java title")
                    .setTitleColor(R.color.black)
                    .setGravityStyle(Gravity.CENTER)
                    .setCanceledOnTouchOutside(false)
                    .setWidth(getScreenWidth()-dpToPx(32))//单独设置宽度
                    //.setWindowSize(getScreenWidth()-dpToPx(32),dpToPx(280)) //整体size
                    .setPositiveButtonMethod("Ok",R.color.white,(d,view) ->{
                        d.dismiss();
                        return null;
                    })
                    .setNegativeButtonMethod("Cancel",R.color.black,(d,view) ->{
                        d.dismiss();
                        return null;
                    })
                    .setFragmentManager(getSupportFragmentManager())
                    ;
            dialog.show();
            
    private int getScreenWidth(){
        return getResources().getDisplayMetrics().widthPixels;
    }

    private int getScreenHeight(){
        return getResources().getDisplayMetrics().heightPixels;
    }

    private int dpToPx(int dp){
        return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,dp,getResources().getDisplayMetrics());
    }

中间圆角+弹窗阴影效果

 BottomAlertDialog dialog = new BottomAlertDialog()
                    .openFullScreenMask(false, R.drawable.bg_dialog_full_radius_14_white,0.1f)//同时使用圆角shape
                    .setBackGroundColor(R.drawable.bg_dialog_full_radius_14_white)
                    //.setCancelBtnGone() //是否隐藏取消按钮
                    .setContent("Exiting out of this form will remove all record information. Would you like to exit anyway?")
                    .setConfirmBg(R.drawable.bg_button_full_green_408)
                    .setCancelBg(R.drawable.bg_button_login_full_border_black_stroke_2)
                    .setTitle("Java title")
                    .setTitleColor(R.color.black)
                    .setGravityStyle(Gravity.CENTER)
                    .setCanceledOnTouchOutside(false)
                    .setWidth(getScreenWidth()-dpToPx(32))
                    //.setWindowSize(getScreenWidth()-dpToPx(32),dpToPx(280))
                    .setPositiveButtonMethod("Ok",R.color.white,(d,view) ->{
                        d.dismiss();
                        return null;
                    })
                    .setNegativeButtonMethod("Cancel",R.color.black,(d,view) ->{
                        d.dismiss();
                        return null;
                    })
                    .setFragmentManager(getSupportFragmentManager())
                    ;
            dialog.show();
