Android 滑动返回Activity的实现代码

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

true
