SlidingUpPanelLayout

介绍：

一个竖直方向的SlidingPanelLayout，支持加载多个Panel，可以灵活地实现漂亮的的交互效果。

运行效果：

使用说明：

1. sample apk

2. gradle

  dependencies {
     // e.g. compile 'com.xw.repo:SlidingUpPanelLayout:1.0.0@aar'
     compile 'com.xw.repo:SlidingUpPanelLayout:${LATEST_VERSION}@aar'
  }

1. java (动态方式)

SlidingUpPanelLayout.setAdapter(new SlidingUpPanelLayout.Adapter() {
      private final int mSize = mWeatherList.size();
      @Override
      public int getItemCount() {
          return mSize;
      }
      @NonNull
      @Override
      public ISlidingUpPanel onCreateSlidingPanel(int position) {
          WeatherPanelView panel = new WeatherPanelView(DemoActivity1.this);
          if (position == 0) {
              panel.setSlideState(EXPANDED);
          } else {
              panel.setSlideState(HIDDEN);
          }
          return panel;
      }
      @Override
      public void onBindView(final ISlidingUpPanel panel, int position) {
          if (mSize == 0)
              return;
          BaseWeatherPanelView BasePanel = (BaseWeatherPanelView) panel;
          BasePanel.setWeatherModel(mWeatherList.get(position));
          BasePanel.setClickable(true);
          BasePanel.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                  if (panel.getSlideState() != EXPANDED) {
                      mSlidingUpPanelLayout.expandPanel();
                  } else {
                      mSlidingUpPanelLayout.collapsePanel();
                  }
              }
          });
      }
  });

Attentions

• 当你的PanelView实现ISlidingUpPanel后，计算需要准确无误才能确保SlidingUpPanelLayout工作正常。通常情况可参考我的demo来改。

• 不要为你的PanelView设置onTouchListener监听，否则可能造成SlidingUpPanelLayout工作异常。

• 不要加载太多的PanelView，因为没有考虑回收机制，过多必然会影响性能。
