android系统自带actionbar总结

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>
