abs_layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/parentlay"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/mytext"
style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:gravity="right"
android:text="test"
android:textColor="#474545"
android:textSize="18sp" />
</LinearLayout>
当我使用此代码设置自定义ActionBar时,一切都很好,并显示在右侧:
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.abs_layout);
但是当我尝试使用充气机在自定义操作栏上更改textview的图块时,文本会停留在左侧:
LayoutInflater mInflater = getLayoutInflater();
View mCustomView = mInflater.inflate(R.layout.abs_layout, null);
TextView tv = mCustomView.findViewById(R.id.mytext);
tv.setText("test");
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(mCustomView);
我希望它在右侧。

尝试一下:

<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
</style>
<style name="CustomTheme" parent="Theme.AppCompat.Light">
<item name="contentInsetStart">0dp</item>
<item name="contentInsetEnd">0dp</item>
</style>
</resources>

注意:在AndroidManifest.xml的application标签内添加以下行。
android:theme="@style/CustomTheme"
