我想尝试从ListView拨打电话，（将“Toast”更改为直接拨打ListView）。
我希望你们帮助我。

ExampleDataSource.java （顺便说一句，我使用的是“ArrayList”）
package com.ngohung.example.models;

import java.util.List;
import com.ngohung.widget.ContactItemInterface;
public class ExampleDataSource {
public static List<ContactItemInterface> getSampleContactList(){
List<ContactItemInterface> list = new ArrayList<ContactItemInterface> ();
list.add(new ExampleContactItem("Polda SULTRA" , "3195040" ,"Sentral PABX jl haluoleo 1" ) );
list.add(new ExampleContactItem("Polda SULTRA" ,"3195041" , "Sentral PABX jl haluoleo 1") );
list.add(new ExampleContactItem("Polda SULTRA" ,"3195042" , "Sentral PABX jl haluoleo 1" ) );
list.add(new ExampleContactItem("Direktorat diklat" , "3190549" , "Sentral PABX jl haluoleo 1") );
list.add(new ExampleContactItem("Direktorat intelkam" , "3190041", "Jl mayjen di panjaitan 1" ) );
list.add(new ExampleContactItem("Direktorat samapta" ,"3005114", "Jl mayjen di panjaitan") );
list.add(new ExampleContactItem("Direktorat lantas" , "3006112" , "Jl mayjen di panjaitan" ) );
list.add(new ExampleContactItem("Direktorat pol air" , "3007604", "Jl mayjen di panjaitan" ) );
return list;
}
}
谢谢..
答案 0 :(得分：2)
为您的AndroidManifest文件添加<uses-permission android:name="android.permission.CALL_PHONE" />权限。
然后只需在列表项单击侦听器中启动一个活动：
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:43..." ));
startActivity(intent);
<强>更新
只需在项目中添加以上代码，然后点击：
@Override
public void onItemClick(AdapterView parent, View v, int position, long id) {
List<ContactItemInterface> searchList = inSearchMode ? filterList : contactList ;
float lastTouchX = listview.getScroller().getLastTouchDownEventX();
if(lastTouchX < 45 && lastTouchX > -1){
Toast.makeText(ContactListActivity.this, "User image is clicked ( " + searchList.get(position).getItemForIndex() + ")", Toast.LENGTH_SHORT).show();
} else
Toast.makeText(ContactListActivity.this, "Nomor: " + searchList.get(position).getItemForIndex() , Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:xxx" ));// replcae "xxx" with the desired number
startActivity(intent);
}
}
