我创建了一个SlidingUpPanel，其中顶层布局中的谷歌地图和底部面板中的列表视图。布局也有一个锚点。我遇到的问题是我多次滑动面板从锚点到倒塌的状态它介于两者之间，我必须多次滑动以从锚定状态转变为崩溃状态。为什么会发生这种情况，我该如何解决这个问题？

我已经尝试过，slideuppanellayout正如您所希望的那样从您的代码中运行。 但如果你仍然无法获得所需的结果，那么你可以添加一个PanelSlideListener并像我一样实现它的方法。
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
private LinearLayout mListLayout;
private SlidingUpPanelLayout mSlidingLayout;
float slideoffset=1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mListLayout = (LinearLayout) findViewById(R.id.main_layout);
mSlidingLayout = (SlidingUpPanelLayout) findViewById(R.id.sliding_layout);
mSlidingLayout.setAnchorPoint(0.4f);
mSlidingLayout.setDragView(mListLayout);
mSlidingLayout.addPanelSlideListener(new SlidingUpPanelLayout.PanelSlideListener() {
@Override
public void onPanelSlide(View panel, float slideOffset) {
slideoffset=slideOffset;
Log.d(TAG, "onPanelSlide: " + slideOffset);
}
@Override
public void onPanelStateChanged(View panel, SlidingUpPanelLayout.PanelState previousState, SlidingUpPanelLayout.PanelState newState) {
Log.d(TAG, "onPanelStateChanged: prevoius state : " + previousState + " new state: " + newState);
if(slideoffset<0.2&&(previousState== SlidingUpPanelLayout.PanelState.ANCHORED||previousState== SlidingUpPanelLayout.PanelState.EXPANDED))
{
mSlidingLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
}
}
});
}
}
首先我从onPanelSlide方法获取slidingOffset并使用此slidingOffset值来确定slidinguppanellayout的当前位置，以便在onPanelStateChanged方法中我可以使用先前的状态和slideOffset值来知道设置结束状态。
如果您在此之后仍然存在问题，那么只需发布logcat。

以下代码适用于我。希望这会有所帮助。
@Override
public void onPanelSlide(View panel, float slideOffset) {
slideoffset=slideOffset;
}
@Override
public void onPanelStateChanged(View panel, SlidingUpPanelLayout.PanelState previousState, SlidingUpPanelLayout.PanelState newState)
{
if(slideoffset<0.2&& previousState == SlidingUpPanelLayout.PanelState.DRAGGING)
{
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
}
else if(slideoffset == 1&& previousState == SlidingUpPanelLayout.PanelState.DRAGGING)
{
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.EXPANDED);
}}
