Window的各种效果

默认的效果

导航栏显示，内容处于导航键上方
style

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

fitSystemWindow

单独使用fitSystemWindow是没有效果的，如下图

fitSystemWindow配合透明状态栏和导航栏

    <style name="TransparentStyle" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowIsTranslucent">true</item>
        <!--设置导航栏/状态栏窗口color为透明-->
        <item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowTranslucentNavigation">true</item>
        <!--        <item name="android:windowNoTitle">true</item>-->



        <item name="android:statusBarColor">@android:color/transparent</item>
        <item name="android:navigationBarColor">@android:color/transparent</item>
        <!-- Customize your theme here. -->
        <!--        <item name="colorPrimary">@color/colorPrimary</item>-->
        <!--        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>-->
        <!--        <item name="colorAccent">@color/colorAccent</item>-->

    </style>

FitsystemWindow内容延申到状态栏

public class NormalFitSystemWindowTransparentCoverNavigationActivity extends AppCompatActivity {
    
    

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    
    
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_fitsystemwindow_transparent_content_tonavigation);
        RelativeLayout backgroundLayout = findViewById(R.id.background_layout);
        FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) backgroundLayout.getLayoutParams();
        layoutParams.bottomMargin = - getRealNavigationBarHeight(this);
        layoutParams.topMargin = - getStatusBarHeight();
        backgroundLayout.setLayoutParams(layoutParams);


    }





    public int getStatusBarHeight() {
    
    
        int result = 0;
        int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
    
    
            result = getResources().getDimensionPixelSize(resourceId);
        }
        return result;
    }


    public static int getRealNavigationBarHeight(Context context) {
    
    
        Resources resources = context.getResources();
        int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
        if (resourceId > 0) {
    
    
            return resources.getDimensionPixelSize(resourceId);
        }
        return 0;
    }



}

最后有一个小技巧补充一下，改变状态栏图标的颜色:

     //切换到浅色状态栏模式，黑字
            getWindow().getDecorView()
                    .setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);

    //切换到深色模式，白字
             getWindow().getDecorView()
                    .setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
