android 全透明式状态栏

全透明状态栏

继上一篇博客fitsystemwindows简单使用之后发现5.0设置如下属性之后 状态栏是半透明的

 if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
        //半透明头部状态栏  布局在状态栏下方
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
 }

在各种尝试之后，终于找到了下面这种方法，这个只试用于5.0

        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Window window = getWindow();
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setStatusBarColor(Color.TRANSPARENT);
        }

Build.VERSION_CODES.LOLLIPOP：5.0

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){//4.4 全透明状态栏
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }

        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {//5.0 全透明实现
            Window window = getWindow();
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setStatusBarColor(Color.TRANSPARENT);//calculateStatusColor(Color.WHITE, (int) alphaValue)
        }
    }
}
