要解决AppBarLayout在底部绘制元素时绘制在导航栏后面的问题,可以按照以下步骤进行处理:
AppBarLayout appBarLayout = findViewById(R.id.appBarLayout);
appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
int navigationBarHeight = getNavigationBarHeight();
// 将底部元素向上移动导航栏的高度
View bottomView = findViewById(R.id.bottomView);
ViewGroup.MarginLayoutParams layoutParams = (ViewGroup.MarginLayoutParams) bottomView.getLayoutParams();
layoutParams.bottomMargin = navigationBarHeight;
bottomView.setLayoutParams(layoutParams);
}
});
private int getNavigationBarHeight() {
int resourceId = getResources().getIdentifier("navigation_bar_height", "dimen", "android");
if (resourceId > 0) {
return getResources().getDimensionPixelSize(resourceId);
}
return 0;
}
通过以上步骤,你可以解决AppBarLayout在底部绘制元素时绘制在导航栏后面的问题。
