android系统自带actionbar小结

android不同的版本引入的actionbar有差异，现总结如下

一、在support.v7包中

引入布局使用onCreateOptionsMenu方法中的参数：inflate

import android.support.v7.app.ActionBarActivity;public class ComboLineColumnChartActivity extends ActionBarActivity {       // MENU        @Override        public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {            inflater.inflate(R.menu.combo_line_column_chart, menu);        }		        @Override        public boolean onOptionsItemSelected(MenuItem item) {            int id = item.getItemId();            if (id == R.id.action_reset) {                reset();                generateData();                return true;            }            if (id == R.id.action_add_line) {                addLineToData();                return true;            }            ......            return super.onOptionsItemSelected(item);        }}

布局文件：

在menu文件夹中

R.menu.combo_line_column_chart

<menu xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    tools:context="lecho.lib.hellocharts.samples.ComboLineColumnChartActivity" >    <item        android:id="@+id/action_reset"        android:title="Reset chart"        app:showAsAction="never"/>    <item        android:id="@+id/action_add_line"        android:title="Add line"        app:showAsAction="never"/>    <item        android:id="@+id/action_toggle_lines"        android:title="Toggle lines/scattered"        app:showAsAction="never"/></menu>

2.在activity中

引入布局要使用activity下的getMenuInflate方法

public class ArticleListActivity extends Activity {    @Override    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.list, menu);        return true;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        int id = item.getItemId();        if (id == R.id.action_settings) {            return true;        }        return super.onOptionsItemSelected(item);    }}

布局代码：

在menu文件夹中

R.menu.list

<menu xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    tools:context=".MyActivity" >    <item android:id="@+id/action_settings"        android:title="@string/action_settings"        android:orderInCategory="100"        android:showAsAction="never" /></menu>
