以编程方式显示和隐藏底表 [英] Show and Hide Bottom Sheet Programmatically

问题描述

我已经使用此解决方案和

I have implemented Bottom Sheet functionality within my activity in onCreate() using this solution and this library

   sheet = new BottomSheet.Builder(this, R.style.BottomSheet_Dialog)
        .title("New")
        .grid() // <-- important part
        .sheet(R.menu.menu_bottom_sheet)
        .listener(new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // TODO
    }
}).build();

现在，我想在单击按钮时显示底页，并且希望以相同的方式在单击同一按钮(如果已经可见)时隐藏底页

Now, I would like to Show Bottom sheet, on click of button and in a same way want to hide bottom sheet on click of same button, if already Visible

推荐答案

在按钮的 onClick()内部使用: sheet.show().

然后，当您要关闭它时，请使用 sheet.dismiss();

Then when you want to dismiss it, use sheet.dismiss();

以下是一个可能的解决方案:

Here below a possible solution:

BottomSheet sheet = new BottomSheet.Builder(...).build();
Button button = (Button)findViewById(R.id.mybutton);
button.setOnClickListener(new OnClickListener(){
    @Override
    public void onClick(View v) {
        //you can use isShowing() because BottomSheet inherit from Dialog class
        if (sheet.isShowing()){
            sheet.dismiss();
        } else {
            sheet.show();    
        }
    }
});
