Question

我想在mainActivity中设置一个自定义ActionBar。我为名为<dependency> <groupId>io.appium</groupId> <artifactId>java-client</artifactId> <version>5.0.4</version> </dependency>  <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>3.11.0</version> </dependency>  <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>6.11</version> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> </project>的操作栏进行了自定义布局。并且宽度在custom_layout中是match_parent，并且在Activity中设置Layoutparams也是MATCH_PARENT。但它仍然在左右两侧留有边距。

Here is My Main Activity

主要活动

custom_header

custom_header.xml

ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayShowTitleEnabled(false);
    actionBar.setDisplayShowCustomEnabled(true);
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

    ActionBar.LayoutParams params = new ActionBar.LayoutParams(
            ActionBar.LayoutParams.MATCH_PARENT,
            ActionBar.LayoutParams.MATCH_PARENT
    );

    View viewActionBar = ((Activity) MainActivity.this).getLayoutInflater().inflate(R.layout.custom_header,null);
    actionBar.setCustomView(viewActionBar,params);

Answer 1

只需添加

Toolbar toolbar=(Toolbar)viewActionBar.getParent();
toolbar.setContentInsetsAbsolute(0,0);

在下面提到的行之后

actionBar.setCustomView(viewActionBar,params);

Answer 2

从RelativeLayout中删除android:padding="10dp"
