自定义Dialog并设置圆角和宽高

效果图：

自定义圆角布局样式：

drawable/bg_dialog_transfer

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="@color/white" />
    <corners android:radius="10dp" />
</shape>

主布局的引用

R.layout.dialog_transfer

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        android:paddingVertical="14dp"
        android:text="转移确认"
        android:textStyle="bold"
        android:textColor="@color/color_0B0B0B"

        app:layout_constraintRight_toLeftOf="@id/tv_sure"
        app:layout_constraintTop_toBottomOf="@id/tv_content" />

    <TextView
        android:id="@+id/tv_sure"
        android:layout_width="80dp"
        android:layout_height="30dp"
        android:layout_marginTop="30dp"
        android:background="@drawable/applyagent_selector"

        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@id/tv_content" />
</android.support.constraint.ConstraintLayout>

在代码中调用：

private void showDialog(){
        if(dialogTransfer == null){
            dialogTransfer = new Dialog(this);
        }
        View view = LayoutInflater.from(this).inflate(R.layout.dialog_transfer, null);
        TextView title = view.findViewById(R.id.tv_title);
        TextView content = view.findViewById(R.id.tv_content);
        TextView sure = view.findViewById(R.id.tv_sure);
        TextView cancle = view.findViewById(R.id.tv_cancle);
        title.setText("转移确认");
        content.setText("品牌卡余额转移目前只支持单向，转移成功后不可转回原品牌卡。");
        sure.setText("确认转移");
        sure.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialogTransfer.dismiss();
            }
        });
        cancle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialogTransfer.dismiss();
            }
        });

        dialogTransfer.setCanceledOnTouchOutside(false);//设置点击透明背景不取消
        dialogTransfer.setContentView(view);
        dialogTransfer.show();

        Window window = dialogTransfer.getWindow();
        WindowManager windowManager = getWindowManager();
        Display d = windowManager.getDefaultDisplay(); // 获取屏幕宽、高度
        WindowManager.LayoutParams attributes = window.getAttributes();

        Point point = new Point();
        d.getSize(point);// 获取屏幕宽、高度到point中
        attributes.width = (int) (point.x * 0.65);//设置宽度占屏幕宽度的0.65倍
        window.setAttributes(attributes);
        window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    }

注意：必须在调用show()方法之后再设置Dialog的宽度、高度才有效！！！

          设置圆角时，必须设置window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
