应用程序标识放置一半在动作条和半mainActivty屏幕上 [英] App logo positioned half in the ActionBar and half on the mainActivty screen

问题描述

能否像这样的机器人可以实现吗？我的猜测是不是因为你可以指定2个不同的布局一个是动作条，一个用于活动，但我可能也被误认为

Can something like this be achieved in Android? my guess is not since you can specify 2 different layouts one for the ActionBar and one for the Activity, but I may also be mistaken

推荐答案

这是一个更坚实的解决方案比 PopupWindow previously建议。

This is a much more solid solution than the PopupWindow previously suggested.

为标志覆盖的布局是一个简单的的ImageView ，上，我们已经设置了点击属性真来prevent触摸事件，从通过传播到查看取值下方。

The layout for the logo overlay is a simple ImageView, on which we've set the clickable attribute to true to prevent touch events from propagating through to Views underneath.

logo.xml 布局：

<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000"
    android:scaleType="fitXY"
    android:src="@drawable/ic_launcher"
    android:clickable="true" />

该方法是指与旧动作条工作，并且依赖于家庭查看作为锚覆盖。它，然而，很容易地修改与工具栏支持类和它的标志查看来工作，虽然这可能是不必要的，因为工具栏类是查看，可以轻松地设置和操作布局XML。

This method is meant to work with the old ActionBar, and relies on the home View as the anchor for the overlay. It is, however, easily modified to work with the support Toolbar class and its logo View, though that is probably unnecessary, since the Toolbar class is a View that can be easily setup and manipulated in layout XML.

private void showLogoOverlay() {
    final View anchor = findViewById(android.R.id.home);
    if(anchor == null) {
        return;
    }

    final View overlay = getLayoutInflater().inflate(R.layout.logo, null, false);
    final ViewGroup decor = (ViewGroup) getWindow().getDecorView();

    anchor.addOnLayoutChangeListener(new OnLayoutChangeListener() {
            @Override
            public void onLayoutChange(View v, int left, int top, int right,
                                       int bottom, int oldLeft, int oldTop,
                                       int oldRight, int oldBottom) {

                int[] offset = new int[2];
                anchor.getLocationOnScreen(offset);

                decor.addView(overlay, 200, 200);
                overlay.setX(offset[0]);
                overlay.setY(offset[1]);

                anchor.removeOnLayoutChangeListener(this);
            }
        }
    );
}
