沉浸式狀態欄設置

1. 在layout中設置

android:fitsSystemWindows="true"

2. 在app的build.gradle中導入

implementation 'com.readystatesoftware.systembartint:systembartint:1.0.3'

3. 可以實現一個BaseActivity，在onCreate中添加：

SystemBarTintManager mTintManager;

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

mTintManager = new SystemBarTintManager(this);
mTintManager.setStatusBarTintEnabled(true);
mTintManager.setTintColor(getResources().getColor(R.color.bg_color));

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