如果我不设置 peekHeight,BottomSheetBehavior 不可拖动
BottomSheetBehavior not draggable if i do not set peekHeight
在我的应用程序中,我有一个底部 sheet 和一个使它成为 collapse/expand 的按钮。
如果未设置peekHeight
底部sheet不可拖动且不会折叠,它始终可见。
代码如下:
View bottomSheet = findViewById(R.id.bottom_sheet1);
mBottomSheetBehavior1 = BottomSheetBehavior.from(bottomSheet);
mBottomSheetBehavior1.setPeekHeight(0); //IF I OMIT THIS, IT DOES NOT WORK
mButton1 = (Button) findViewById(R.id.button_1);
mButton1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(mBottomSheetBehavior1.getState() != BottomSheetBehavior.STATE_EXPANDED) {
mBottomSheetBehavior1.setState(BottomSheetBehavior.STATE_EXPANDED);
mButton1.setText("Collapse 1");
}
else {
mBottomSheetBehavior1.setState(BottomSheetBehavior.STATE_COLLAPSED);
mButton1.setText("Expand 1");
}
}
});
怎么了?
默认情况下,BottomSheetBehavior
不是 hideable。
您必须明确说明您希望该行为可隐藏:
bottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
bottomSheetBehavior.setHideable(true);
