Android未接电话(未接电话个数,以及未接电话信息的读取)

16lz 2021-01-26

1.未接电话的产生

/*
* 未接来电不能用* Observer监听，不过当有新的未接来电时，系统会发送一个广播com.android
* .phone.NotificationMgr.MissedCall_intent（
* 锁屏上显示的未接来电数量就是通知监听这个广播实现的）
*/

因此基于广播----->/*
final IntentFilter filter = new IntentFilter();
filter.addAction("com.android.phone.NotificationMgr.MissedCall_intent");
final Application application = getApplication();
application.registerReceiver(
new BroadcastReceiver() {
@Override
public void onReceive(Context context,Intent intent) {
String action = intent.getAction();
if (action != null&& "com.android.phone.NotificationMgr.MissedCall_intent".equals(action)) {
int mMissCallCount = intent.getExtras().getInt("MissedCallNumber");
Toast.makeText(CallPhoneActivity.this, mMissCallCount+"",Toast.LENGTH_SHORT).show();
}
}
}, filter);*/--------------但是只能说亲测无效，未接受 .....

2.读取未接电话的个数

private int readMissCall() {
result = 0;
// Cursor cursor = getContentResolver().query(CallLog.Calls.CONTENT_URI,
// new String[] { Calls.TYPE }, " type=? and new=?",
// new String[] { Calls.MISSED_TYPE + "", "1" }, "date desc");
Cursor cursor = getContentResolver().query(CallLog.Calls.CONTENT_URI,
new String[] { Calls.TYPE }, " type=?",
new String[] { Calls.MISSED_TYPE + ""}, "date desc");

if (cursor != null) {
result = cursor.getCount();
cursor.close();
}
return result;
}

注意被注释掉的cursor的区别，限定了Call.New（android.provider.CallLog.Calls.NEW）,会使得你过短时间，未接电话的读取个数清空，没有仔细研究过这个变量的具体定义，也懒得理解了..注意Call.New>0

若是想深入的了解，可以访问http://www.apihome.cn/api/android/CallLog.Calls.html.

3.未接电话相关信息的读取-----一些参数还得参照http://www.apihome.cn/api/android/CallLog.Calls.html

contactlist.clear();
final String[] projection = null;

final String selection = null;
final String[] selectionArgs = null;
final String sortOrder = android.provider.CallLog.Calls.DATE + " DESC";
Cursor cursor = null;
try {

cursor = getContentResolver().query(
Uri.parse("content://call_log/calls"), projection,
selection, selectionArgs, sortOrder);
while (cursor.moveToNext()) {
callName= cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.CACHED_NAME));
String callLogID = cursor.getString(cursor
.getColumnIndex(android.provider.CallLog.Calls._ID));
callNumber = cursor.getString(cursor
.getColumnIndex(android.provider.CallLog.Calls.NUMBER));
//需要对时间进行一定的处理
callDate = cursor.getString(cursor
.getColumnIndex(android.provider.CallLog.Calls.DATE));
long callTime = Long.parseLong(callDate);
SimpleDateFormat sdf = new SimpleDateFormat(
"M-dd HH:mm");
callDate = sdf.format(new Date(callTime));

callType = cursor.getString(cursor
.getColumnIndex(android.provider.CallLog.Calls.TYPE));
String isCallNew = cursor.getString(cursor
.getColumnIndex(android.provider.CallLog.Calls.NEW));

// if (Integer.parseInt(callType) == (CallLog.Calls.MISSED_TYPE)
// && Integer.parseInt(isCallNew) > 0) //通过call.new进行了限定，会对读取有一些问题，要删掉该限定
if (Integer.parseInt(callType) == (CallLog.Calls.MISSED_TYPE))
{
//textView.setText(callType+"|"+callDate+"|"+callNumber+"|");

//只是以最简单ListView显示联系人的一些数据----适配器的如何配置可查看http://blog.csdn.net/cl18652469346/article/details/52237637
contactlist.add(callName+"----"+callDate+"----"+callNumber+"----"+"callType:"+callType);
}
}
} catch (Exception e) {
e.printStackTrace();
}
finally {
cursor.close();
}.

}

未接电话的属性很多，可以自行查看已给出的链接，当然少不了数据格式的转换，比如Call.DATE(转换如上)
