android - 从 anchor 滑动到折叠状态时，Umano SlidingUpPanel 卡住

Question

我创建了一个 SlidingUpPanel它由顶部布局中的谷歌地图和底部面板中的 ListView 组成。布局也有一个 anchor 。我遇到的问题是，很多时候当我将面板从 anchor 滑动到折叠状态时，它会卡在中间，这样我必须多次滑动才能从 anchor 移动到折叠状态。为什么会发生这种情况，我该如何解决？

我已经尝试过，并且 slidinguppanellayout 正在按照您希望的代码工作。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 值来了解设置的结束状态。

If you still persist problem after this then just post out the logcat.
