我必须创建一个类似于android的通话记录的活动。我没有找到很多关于它的信息。我发现的是这个例子，它有一个主要活动，有3个按钮：
1-外拨电话清单 2-拨打电话清单 3-未接来电列表
每个按钮发送到另一个活动，其中包含每个电话的详细信息。
但我需要的是，首先将所有这个应用程序统一到一个唯一的布局中，一次显示所有错过的，outoging和ingoing调用，按日期列出。我现在认为这应该很简单，但是我无法做到这一点，这是因为我向你寻求帮助。接下来我要做的就是修改listview布局，以便在android显示时显示调用日志，并显示电话图标以及触摸该名称时调用该人的选项。
但首先，我需要以我需要的方式运行应用程序。
这是主布局的代码，其中有3个按钮：
public class CallLogsDemoActivity extends Activity {
public static ArrayList<CallLogModel> outgoingList;
public static ArrayList<CallLogModel> incomingList;
public static ArrayList<CallLogModel> missedcallList;
public static final int OUTGOING_CALLS = 1;
public static final int INCOMING_CALLS = 2;
public static final int MISSED_CALLS = 3;
public static final String CALL_TYPE = "TYPE";
private Button inBtn, outBtn, missedBtn;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
outBtn = (Button) findViewById(R.id.button1);
inBtn = (Button) findViewById(R.id.button2);
missedBtn = (Button) findViewById(R.id.button3);
inBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showIncomingList();
}
});
outBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showOutGoingList();
}
});
missedBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showMissedList();
}
});
outgoingList = new ArrayList<CallLogModel>();
incomingList = new ArrayList<CallLogModel>();
missedcallList = new ArrayList<CallLogModel>();
new ReadLogs().execute();
}
private void showIncomingList() {
Intent intent = new Intent(this, CallLogs.class);
intent.putExtra(CALL_TYPE, INCOMING_CALLS);
startActivity(intent);
}
private void showMissedList() {
Intent intent = new Intent(this, CallLogs.class);
intent.putExtra(CALL_TYPE, MISSED_CALLS);
startActivity(intent);
}
private void showOutGoingList() {
Intent intent = new Intent(this, CallLogs.class);
intent.putExtra(CALL_TYPE, OUTGOING_CALLS);
startActivity(intent);
}
private String getDuration(long milliseconds) {
int seconds = (int) (milliseconds / 1000) % 60;
int minutes = (int) ((milliseconds / (1000 * 60)) % 60);
int hours = (int) ((milliseconds / (1000 * 60 * 60)) % 24);
if (hours < 1)
return minutes + ":" + seconds;
return hours + ":" + minutes + ":" + seconds;
}
private String getDateTime(long milliseconds) {
Date date = new Date(milliseconds);
//return DateFormat.getDateTimeInstance().format(new Date());
return date.toLocaleString();
}
private void readCallLogs() {
missedcallList.clear();
incomingList.clear();
outgoingList.clear();
Cursor callLogCursor = getContentResolver().query(
android.provider.CallLog.Calls.CONTENT_URI, null, null, null,
android.provider.CallLog.Calls.DEFAULT_SORT_ORDER);
if (callLogCursor != null) {
while (callLogCursor.moveToNext()) {
String id = callLogCursor.getString(callLogCursor
.getColumnIndex(CallLog.Calls._ID));
String name = callLogCursor.getString(callLogCursor
.getColumnIndex(CallLog.Calls.CACHED_NAME));
String cacheNumber = callLogCursor.getString(callLogCursor
.getColumnIndex(CallLog.Calls.CACHED_NUMBER_LABEL));
String number = callLogCursor.getString(callLogCursor
.getColumnIndex(CallLog.Calls.NUMBER));
long dateTimeMillis = callLogCursor.getLong(callLogCursor
.getColumnIndex(CallLog.Calls.DATE));
long durationMillis = callLogCursor.getLong(callLogCursor
.getColumnIndex(CallLog.Calls.DURATION));
int callType = callLogCursor.getInt(callLogCursor
.getColumnIndex(CallLog.Calls.TYPE));
String duration = getDuration(durationMillis * 1000);
String dateString = getDateTime(dateTimeMillis);
if (cacheNumber == null)
cacheNumber = number;
if (name == null)
name = "No Name";
CallLogModel callLogModel = new CallLogModel(name, cacheNumber,
duration, dateString);
if (callType == CallLog.Calls.OUTGOING_TYPE) {
outgoingList.add(callLogModel);
} else if (callType == CallLog.Calls.INCOMING_TYPE) {
incomingList.add(callLogModel);
} else if (callType == CallLog.Calls.MISSED_TYPE) {
missedcallList.add(callLogModel);
}
}
callLogCursor.close();
}
}
private class ReadLogs extends AsyncTask<Void, Void, Void> {
/* Object */
ProgressDialog dialog;
/*
* Function name: onPreExecute Parameters: Void params Return: void
*/
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
dialog = ProgressDialog.show(CallLogsDemoActivity.this,
"Reading Call Logs...", "Please wait...", true);
}
/*
* Function name: doInBackground Parameters: Void params Return: void
*/
@Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
readCallLogs();
return null;
}
/*
* Function name: onPostExecute Parameters: Void result Return: void
*/
@Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
dialog.dismiss();
}
}
}
这是显示清单的其他活动：
public class CallLogs extends Activity {
private ListView mainListView;
private ArrayAdapter<CallLogModel> listAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
mainListView = (ListView) findViewById(R.id.listView);
mainListView.setSmoothScrollbarEnabled(true);
Bundle extras = getIntent().getExtras();
int callType = extras.getInt(CallLogsDemoActivity.CALL_TYPE);
if (callType == CallLogsDemoActivity.OUTGOING_CALLS)
listAdapter = new CallLogsArrayAdapter(this,
CallLogsDemoActivity.outgoingList);
else if (callType == CallLogsDemoActivity.INCOMING_CALLS)
listAdapter = new CallLogsArrayAdapter(this,
CallLogsDemoActivity.incomingList);
else if (callType == CallLogsDemoActivity.MISSED_CALLS)
listAdapter = new CallLogsArrayAdapter(this,
CallLogsDemoActivity.missedcallList);
mainListView.setAdapter(listAdapter);
}
public void initElements() {
listAdapter.notifyDataSetChanged();
}
}
如上所述，我试图统一这段代码，以便在一个布局中显示并一次显示所有调用条件，就像android那样，但是不要实现它。
答案 0 :(得分：1)
更改此代码
int callType = extras.getInt(CallLogsDemoActivity.CALL_TYPE);
if (callType == CallLogsDemoActivity.OUTGOING_CALLS)
listAdapter = new CallLogsArrayAdapter(this,
CallLogsDemoActivity.outgoingList);
else if (callType == CallLogsDemoActivity.INCOMING_CALLS)
listAdapter = new CallLogsArrayAdapter(this,
CallLogsDemoActivity.incomingList);
else if (callType == CallLogsDemoActivity.MISSED_CALLS)
listAdapter = new CallLogsArrayAdapter(this,
CallLogsDemoActivity.missedcallList);
mainListView.setAdapter(listAdapter);
到此
int callType = extras.getInt(CallLogsDemoActivity.CALL_TYPE);
ArrayList<CallLogModel> collectiveList = new ArrayList<CallLogModel>();
collectiveList.addAll(CallLogsDemoActivity.outgoingList);
collectiveList.addAll(CallLogsDemoActivity.incomingList);
collectiveList.addAll(CallLogsDemoActivity.missedcallList);
listAdapter = new CallLogsArrayAdapter(this,collectiveList);
mainListView.setAdapter(listAdapter);
