与其他图标相比,AppCompat ShareActionProvider图标太大

Question

我将ActionBarSherlock更改为AppCompat v7.我已经完成了使其工作所需的所有更改,但是使用共享图标(使用ShareActionProvider)发生了一些奇怪的事情.与其他图标相比,共享图标太大.我也使用支持库进行搜索,其大小正确.问题在于共享图标.

my_menu.xml:

    <menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:moblee="http://schemas.android.com/apk/res-auto" >
    <item
        android:id="@+id/menu_share"
        android:padding="10dp"
        android:title="@string/menu_share"
        moblee:actionProviderClass="android.support.v7.widget.ShareActionProvider"
        moblee:showAsAction="always"/>
    <item
        android:id="@+id/menu_search"
        android:title="@string/menu_search"
        moblee:actionViewClass="android.support.v7.widget.SearchView"
        moblee:showAsAction="always"/>
</menu>

分段:

public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.my_menu, menu);
    MenuItem item = menu.findItem(R.id.menu_share);
    ShareActionProvider shareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
    shareActionProvider.setShareIntent(getDefaultShareIntent());
}

styles.xml

Answer 1

材料设计中的图标为24dp x 24dp,正如所反映的那样SearchView.但是,ShareActionProvider默认情况下尚未更新为材料设计.

您可以actionModeShareDrawable在主题中设置以在以下位置设置共享图标ShareActionProvider:

<item name="actionModeShareDrawable">@drawable/share_icon</item>

请注意,ShareActionProvider在材料设计指南中没有找到任何地方,并且Android M的直接共享功能(此时需要您使用标准共享意图),目前还不清楚这是否ShareActionProvider是建议的模式.

我最终使用的解决方案不再使用ShareContentProvider，而是使用Intent.createChooser(). 进行这些更改非常简单，它会打开新的共享对话框，如下所示：

操作栏中的共享图标：

对话：

菜单文件

<item
    android:id="@+id/menu_share"
    android:checkable="true"
    android:icon="@drawable/ic_menu_share"
    myapp:showAsAction="always"
    android:title="@string/menu_share"/>

片段类：

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int itemId = item.getItemId();
    if (itemId == R.id.menu_share) {
        showShareDialog();
    }
        return super.onOptionsItemSelected(item);
}

private void showShareDialog(String message) {
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_SEND);
    intent.setType("text/plain");

    intent.putExtra(Intent.EXTRA_SUBJECT, mTitle);
    intent.putExtra(Intent.EXTRA_TEXT, mMessage);

    startActivity(Intent.createChooser(intent, getString(R.string.menu_share)));
}
