app_bar.xml

  <?xml version="1.0" encoding="utf-8"?>
   <android.support.v7.widget.Toolbar
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:background="@color/primaryColor"
   android:minHeight="?attr/actionBarSize"
   android:paddingTop="@dimen/app_bar_top_padding"
   android:theme="@style/ToolBarStyle"/>

样式.xml

<resources xmlns:android="http://schemas.android.com/apk/res/android">

菜单选项.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">


<item android:id="@+id/homes"
    android:title="homes"
    android:icon="@drawable/ic_action_home1"
    app:showAsAction="always"/>

<item android:id="@+id/profilepreview"
    android:title="ProfilePreview"

</menu>

主 Activity .java

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_option, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {

            case R.id.profilepreview:
            startActivity(new Intent(this, ProfilePreview.class));
            return true;

            case R.id.homes:
            mFragment = new HomeFragment();
            break;

            case R.id.findPeople:
            mFragment = new FindFriendsFragment();
            break;

            case R.id.log:
            M.logOut(this);
            mIntent = new Intent(this, LoginActivity.class);
            finish();

    }

    if (mFragment != null && mIntent == null) {
        mFragmentManager = getFragmentManager();
        mFragmentManager.beginTransaction()
                .replace(R.id.frameContainer, mFragment).commit();
    } else {
        startActivity(mIntent);
        mIntent = null;
    }return super.onOptionsItemSelected(item);
    }

您可以设计自定义布局并将其添加为您的操作布局。还要确保您没有在 menu.xml 文件中添加任何图标。

<item android:id="@+id/homes"
android:title="homes"
app:actionLayout="@layout/your_custom_layout"
app:showAsAction="always"/>

然后在您的自定义布局中提供 min_height。
