A. Android编程，根据姓名获得手机通讯录中的电话号码

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP

intent.putExtras(extras);
}
context.startActivity(intent);
}

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_phone_name);
et=(EditText)this.findViewById(R.id.mobile);
}

publicvoidgetTelClick(Viewview){
Stringname=et.getText().toString().trim();
number(name);
}

/**

publicvoidnumber(Stringname){
//使用ContentResolver查找联系人数据
Cursorcursor=getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null,null,null,null);
//遍历查询结果，找到所需号码
while(cursor.moveToNext()){
//获取联系人ID
StringcontactId=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
//获取联系人的名字
StringcontactName=cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
if(name.equals(contactName)){
//使用ContentResolver查找联系人的电话号码
Cursorphone=getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID+"="+contactId,null,null);
if(phone.moveToNext()){
StringphoneNumber=phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Toast.makeText(this,phoneNumber+"TeachCourse——blog。。。",Toast.LENGTH_SHORT).show();
Log.d(TAG,"电话："+phoneNumber);
break;
}

}
}
}
}

1、修改getTelClick()方法

2、修改Toast面包屑提示

3、修改获取联系人名字方法

4、位置稍微调整
