操作栏，默认情况下按钮会向右捕捉，如何将它们分开

Question

我摆脱了操作栏上的图标和标签，并有3个按钮导航到应用程序的某些部分。问题是按钮都被压扁到动作栏的一侧！我怎么把它隔开？我很乐意在动作栏左侧有一个，中间一个，右边一个。让我的用户看起来更干净整洁：）

Answer 1

做以下事情，

 public boolean onCreateOptionsMenu(Menu menu) {        
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);

// ...

// Find the icon(Button); make it aligned to right or left or center, also in expanded mode:

<"your bttn">.setLayoutParams(new ActionBar.LayoutParams(Gravity.RIGHT));
<"your bttn2">.setLayoutParams(new ActionBar.LayoutParams(Gravity.LEFT));
<"your bttn3">.setLayoutParams(new ActionBar.LayoutParams(Gravity.CENTER));

}
