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：
