Android仿微信activity滑动关闭效果

Android仿微信activity滑动关闭功能

1.利用具体利用v4包下的slidingPaneLayout实现透明的activity，代码如下：

BaseActivity:
public class BaseSlideCloseActivity extends AppCompatActivity implements
 SlidingPaneLayout.PanelSlideListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
 initSlideBackClose();
 super.onCreate(savedInstanceState);
}

private void initSlideBackClose() {
 if (isSupportSwipeBack()) {
  SlidingPaneLayout slidingPaneLayout = new SlidingPaneLayout(this);
  // 通过反射改变mOverhangSize的值为0，
  // 这个mOverhangSize值为菜单到右边屏幕的最短距离，
  // 默认是32dp，现在给它改成0
  try {
   Field overhangSize = SlidingPaneLayout.class.getDeclaredField("mOverhangSize");
   overhangSize.setAccessible(true);
   overhangSize.set(slidingPaneLayout, 0);
  } catch (Exception e) {
   e.printStackTrace();
  }
  slidingPaneLayout.setPanelSlideListener(this);
  slidingPaneLayout.setSliderFadeColor(getResources()
    .getColor(android.R.color.transparent));

// 左侧的透明视图
  View leftView = new View(this);
  leftView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
  slidingPaneLayout.addView(leftView, 0);

ViewGroup decorView = (ViewGroup) getWindow().getDecorView();

// 右侧的内容视图
  ViewGroup decorChild = (ViewGroup) decorView.getChildAt(0);
  decorChild.setBackgroundColor(getResources()
    .getColor(android.R.color.white));
  decorView.removeView(decorChild);
  decorView.addView(slidingPaneLayout);

// 为 SlidingPaneLayout 添加内容视图
  slidingPaneLayout.addView(decorChild, 1);
 }
}

protected boolean isSupportSwipeBack() {
 return true;
}

@Override
public void onPanelSlide(View panel, float slideOffset) {

}

@Override
public void onPanelOpened(View panel) {
 finish();
}

@Override
public void onPanelClosed(View panel) {

}
}

activity 透明style：
