为了写项目的额简便性，我们需要对代码做一下封装

1：BaseActivity的封装

public  abstract class MybaseActivity extends Activity implements View.OnClickListener {

    /***封装toast对象**/
    private static Toast toast;
    /***是否显示标题栏*/
    private  boolean isshowtitle = true;
    /***是否显示状态栏栏*/
    private  boolean isshowstate = true;
    /*
       设置是否允许全屏
     */
    private boolean mAllowFullScreen = true;

    /** 是否沉浸状态栏 **/
    private boolean isSetStatusBar = true;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if(!isshowtitle){
            requestWindowFeature(Window.FEATURE_NO_TITLE);
        }
          //沉浸式
        if (isSetStatusBar) {
            steepStatusBar();
        }
          //是否允许全屏
        if (mAllowFullScreen) {
            this.getWindow().setFlags(
                    WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
            requestWindowFeature(Window.FEATURE_NO_TITLE);
        }
        if(isshowstate){
            getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,
                    WindowManager.LayoutParams. FLAG_FULLSCREEN);
        }
        setContentView(intiLayout());//设置布局
           initView();
           initData();
    }

      /*
         判断版本号，版本号小于19不好使
       */
    private void steepStatusBar() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

                    WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);

    }
