侧滑

1.全屏

Window window = getWindow();
        //隐藏标题栏
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        //隐藏状态栏
        //定义全屏参数
        int flag= WindowManager.LayoutParams.FLAG_FULLSCREEN;
        //设置当前窗体为全屏显示
        window.setFlags(flag, flag);
        setContentView(R.layout.activity_main);  //必须在setContentView之前

2.去DrawerLayout阴影

 mDrawerLayout.setScrimColor(Color.TRANSPARENT); //去掉DrawerLayout阴影效果

3.设置DrawerLayout主页面移动

 mDrawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {
            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {
                //主页面移动
                mMainLayout.setX(slideOffset * drawerView.getWidth());
            }

            @Override
            public void onDrawerOpened(View drawerView) {

            }

            @Override
            public void onDrawerClosed(View drawerView) {

            }

            @Override
            public void onDrawerStateChanged(int newState) {

            }
        });

4.Toolbar menu按钮显示 及 点击按钮时打开侧滑菜单

  ActionBar actionBar = getSupportActionBar(); //设置menu按钮显示
        if(actionBar != null){
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setHomeAsUpIndicator(R.drawable.menu);
        }


  @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()){
            case android.R.id.home:
                mDrawerLayout.openDrawer(GravityCompat.START);
                break;
                default: break;
        }
        return true;
