java - setStatusBarColor 不起作用

Question

所以我想做一个透明的状态栏。问题是，状态栏总是变成黑色。我使用了 setStatusBarColor() 方法，但没有帮助。这就是我最终得到的结果。

这是 Activity 的类:

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    /*if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    }*/
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        Window w = getWindow(); // in Activity's onCreate() for instance
        w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
        getWindow().setStatusBarColor(Color.TRANSPARENT);

    }else {
        FrameLayout relativeLayout = (FrameLayout) findViewById(R.id.mainStatusBar);
        relativeLayout.setVisibility(View.GONE);
    }
    CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
            .setDefaultFontPath("SourceSansPro-Regular.otf")
            .setFontAttrId(R.attr.fontPath)
            .build()
    );

}
@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));
}


}

使用此代码使透明

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        Window window = getWindow();
        window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    }

并在 list 中使用 NoActionBar 主题。
