android 电话号码的获取及拨打电话


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>
