Android 滑动返回Activity的实现代码

近来玩微信的时候偶然发现，向左滑动朋友圈竟然可以返回主页，故引起兴趣特研究

代码很简洁

package com.example.wyj.cainiaoshopping.activity;import android.support.annotation.Nullable;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import com.example.wyj.cainiaoshopping.R;import me.imid.swipebacklayout.lib.SwipeBackLayout;import me.imid.swipebacklayout.lib.app.SwipeBackActivity;public class SwiftActivity extends SwipeBackActivity { private SwipeBackLayout mSwipeBackLayout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_swift); mSwipeBackLayout = getSwipeBackLayout(); int edgeFlag = SwipeBackLayout.EDGE_LEFT; mSwipeBackLayout.setEdgeTrackingEnabled(edgeFlag); // saveTrackingMode(edgeFlag); }}

绑定远程仓库

compile 'me.imid.swipebacklayout.lib:library:1.0.0'

另外Activity的主题也要设置

<item name="Android:windowIsTranslucent">true</item>

最后继承使用即可
