Summary of built-in actionbar in android system

The actionbar introduced by different android versions is different. The following is a summary:

1. In the support. v7 package

Introduce layout using the parameter inflate in the onCreateOptionsMenu Method

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);        }}

2. In activity

To introduce the layout, use the getMenuInflate method under the activity.

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);    }}
