我创建了一个SlidingUpPanel，它由顶部布局中的google地图和底部面板中的列表视图组成。布局也有一个锚点。我遇到的问题是，很多时候我从锚点滑动面板到折叠状态时，它卡在两者之间，以至于我必须多次滑动才能从锚点移动到折叠状态。为什么会发生这种情况，我该如何解决这个问题？

我已经尝试过了，滑动面板布局正在按照您想要的代码工作。但是，如果您仍然无法获得所需的结果，那么您可以添加一个 PanelSlideListener 并像我一样实现其方法。
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 sslideingOffset 并使用此 sslideingOffset 值来确定滑动uppanellayout的当前位置，以便在 onPanelStateChanged 方法中，我可以使用以前的状态和 slideOffset 值来了解设置结束状态。
如果在此之后您仍然有问题，那么只需发布日志猫即可。
以下代码对我有用。希望这有帮助。
@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);
}}
