在Java
public class MainActivity extends Activity {
ListView listView;
ContentResolver content;
private static final String[] PHONES_PROJECTION=new String[]{
Phone.DISPLAY_NAME,Phone.NUMBER,Photo.PHOTO_ID,Phone.CONTACT_ID
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
listView=(ListView)findViewById(R.id.list);
content=getContentResolver();
//获取手机的信息
Cursor cursor=content.query(Phone.CONTENT_URI, null, null, null, null);
SimpleCursorAdapter simpleCursorAdapter=new SimpleCursorAdapter(MainActivity.this, R.layout.listitem, cursor, new String[]{Phone.DISPLAY_NAME,Phone.NUMBER}, new int[]{R.id.textname,R.id.textnumber}, 0);
listView.setAdapter(simpleCursorAdapter);
//打电话
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View view, int position,
long arg3) {
TextView textView=(TextView)view.findViewById(R.id.textnumber);
Intent intent=new Intent();
intent.setAction(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:"+textView.getText().toString()));
startActivity(intent);
}
});
}
在activity_main 文件
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.contentprovider.MainActivity" >
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</RelativeLayout>
在创建listitem.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<TextView
android:id="@+id/textname"
android:layout_width="wrap_content"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="hh"/>
<TextView
android:id="@+id/textnumber"
android:layout_weight="1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="hh"/>
</LinearLayout>
