自由窗口相关修改 AndroidQ

1 打开自由窗口相关配置

// frameworks/base/services/core/java/com/android/server/wm/ActivityTaskManagerService.java
public void retrieveSettings(ContentResolver resolver) {
   
   
    // wugm: enable free form setting
    Settings.Global.putInt(resolver, DEVELOPMENT_ENABLE_FREEFORM_WINDOWS_SUPPORT, 1);
    Settings.Global.putInt(resolver, DEVELOPMENT_FORCE_RESIZABLE_ACTIVITIES, 1);
    final boolean freeformWindowManagement =
    mContext.getPackageManager().hasSystemFeature(FEATURE_FREEFORM_WINDOW_MANAGEMENT)
        || Settings.Global.getInt(
        resolver, DEVELOPMENT_ENABLE_FREEFORM_WINDOWS_SUPPORT, 0) != 0;
    // 省略部分
}

<!--frameworks/base/core/res/res/values/config.xml-->
<bool name="config_freeformWindowManagement">true</bool>

2 窗口控制栏布局方式

标题是否直接悬浮显示在内容上，而不是下推内容

// frameworks/base/core/java/com/android/internal/widget/DecorCaptionView.java
public void setPhoneWindow(PhoneWindow owner, boolean show) {
   
   
    mOwner = owner;
    mShow = show;
    if (SystemProperties.getBoolean("persist.sys.freeform", true)) {
   
   
        owner.setOverlayWithDecorCaptionEnabled(false);
    }
    mOverlayWithAppContent = owner.isOverlayWithDecorCaptionEnabled();
    if (mOverlayWithAppContent) {
   
   
        mCaption.setBackgroundColor(Color.TRjavaANSPARENT);
    } else {
   
   
        mCaption.setBackgroundColor(Color.GRAY);
    }
    updateCaptionVisibility();
    // 省略部分
}

3 自由窗口圆角切换

设置圆角矩形

// frameworks/base/core/java/com/android/internal/policy/DecorView.java
private static final ViewOutlineProvider FREEFORM_OUTLINE_PROVIDER = new ViewOutlineProvider() {
   
   
    @Override
    public void getOutline(View view, Outline outline) {
   
   
        outline.setRoundRect(0, 0, view.getWidth(), view.getHeight(), 20);
        outline.setAlpha(1f);
    }
};
private void setDecorCaptionShade(DecorCaptionView view) {
   
   
    setClipToOutline(true)
