注意截图的位置参数
AppBarLayout的监听方法
import com.google.android.material.appbar.AppBarLayout;
public abstract class AppBarStateChangeListener implements AppBarLayout.OnOffsetChangedListener {
public enum State {
EXPANDED,
COLLAPSED,
IDLE
}
private State mCurrentState = State.IDLE;
@Override
public final void onOffsetChanged(AppBarLayout appBarLayout, int i) {
if (i == 0) {
if (mCurrentState != State.EXPANDED) {
onStateChanged(appBarLayout, State.EXPANDED);
}
mCurrentState = State.EXPANDED;
} else if (Math.abs(i) >= appBarLayout.getTotalScrollRange()) {
if (mCurrentState != State.COLLAPSED) {
onStateChanged(appBarLayout, State.COLLAPSED);
}
mCurrentState = State.COLLAPSED;
} else {
if (mCurrentState != State.IDLE) {
onStateChanged(appBarLayout, State.IDLE);
}
mCurrentState = State.IDLE;
}
}
public abstract void onStateChanged(AppBarLayout appBarLayout, State state);
}
使用
binding.appbarlayout.addOnOffsetChangedListener(new AppBarStateChangeListener() {
@Override
public void onStateChanged(AppBarLayout appBarLayout, State state) {
if (state == State.EXPANDED) {
//展开
} else if (state == State.COLLAPSED) {
//关闭
}
}
});
