我的主要目的是读取设备的通话记录，并使用recyclerview和cardview将其显示给用户。但是，当我在marshmallow设备应用程序上运行时，会强制关闭。这是我在6.0上运行时用来读取通话记录和错误的代码
我的MainActivity看起来像：
public class MainActivity extends AppCompatActivity implements Callbacks {
ArrayList<CallLogItem> mItems = new ArrayList<>();
private RecyclerView mRecyclerView;
private RecyclerView.LayoutManager mLayoutManager;
private RecyclerView.Adapter mAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.calllog);
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
getCallDetails();
}
private void getCallDetails() {
String strOrder = CallLog.Calls.DATE + " DESC";
Cursor managedCursor = managedQuery(CallLog.Calls.CONTENT_URI, null, null, null, strOrder);
int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);
int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
while (managedCursor.moveToNext()) {
String phNum = managedCursor.getString(number);
String callTypeCode = managedCursor.getString(type);
String strcallDate = managedCursor.getString(date);
Date callDate = new Date(Long.valueOf(strcallDate));
String callDuration = managedCursor.getString(duration);
String callType = null;
int callcode = Integer.parseInt(callTypeCode);
switch (callcode) {
case CallLog.Calls.OUTGOING_TYPE:
callType = "Outgoing";
break;
case CallLog.Calls.INCOMING_TYPE:
callType = "Incoming";
break;
case CallLog.Calls.MISSED_TYPE:
callType = "Missed";
break;
}
CallLogItem callLogItem = new CallLogItem();
callLogItem.setPhoneNumber(phNum);
callLogItem.setCallDate(String.valueOf(callDate));
callLogItem.setCallType(callType);
callLogItem.setCallDuration(callDuration);
mItems.add(callLogItem);
mAdapter = new CallLogAdapter(mItems, this);
mRecyclerView.setAdapter(mAdapter);
}
managedCursor.close();
}
@Override
public void onCustomClick(CallLogItem callLogItem) {
Toast.makeText(getApplicationContext(), "" + callLogItem.getPhoneNumber(), Toast.LENGTH_LONG).show();
}
@Override
public void onCustomLongClick(CallLogItem callLogItem) {
}}
我的适配器类如下：
public class CallLogAdapter extends RecyclerView.Adapter<CallLogAdapter.ViewHolder> {
private List<CallLogItem> mItems;
private Callbacks mCallbacks;
public CallLogAdapter(ArrayList<CallLogItem> mItems, Callbacks callbacks) {
this.mItems = mItems;
this.mCallbacks = callbacks;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext())
.inflate(R.layout.bookmark_card_item, viewGroup, false);
ViewHolder viewHolder = new ViewHolder(v);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {
CallLogItem callLogItem = mItems.get(position);
viewHolder.phoneNumber.setText("Phone Number: " + callLogItem.getPhoneNumber());
viewHolder.callDuration.setText("Call Duration(In Sec): " + callLogItem.getCallDuration());
viewHolder.callDate.setText("Call Date: " + callLogItem.getCallDate());
viewHolder.callType.setText("Call Type: " + callLogItem.getCallType());
}
@Override
public int getItemCount() {
return mItems.size();
}
class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener {
public View view;
public TextView phoneNumber, callDuration, callDate, callType;
public ViewHolder(View itemView) {
super(itemView);
this.view = itemView;
phoneNumber = (TextView) itemView.findViewById(R.id.phoneNumber);
callDuration = (TextView) itemView.findViewById(R.id.callDuration);
callDate = (TextView) itemView.findViewById(R.id.callDate);
callType = (TextView) itemView.findViewById(R.id.callType);
view.setOnLongClickListener(this);
view.setOnClickListener(this);
}
// onCustomClick Listener for view
@Override
public void onClick(View v) {
int position = getAdapterPosition();
CallLogItem callLogItem = mItems.get(position);
mCallbacks.onCustomClick(callLogItem);
}
//onLongClickListener for view
@Override
public boolean onLongClick(View v) {
int position = getAdapterPosition();
CallLogItem callLogItem = mItems.get(position);
mCallbacks.onCustomLongClick(callLogItem);
return true;
}
}}
我的POJO类如下：
public class CallLogItem {
private String phoneNumber;
private String callType;
private String callDate;
private String callDuration;
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getCallType() {
return callType;
}
public void setCallType(String callType) {
this.callType = callType;
}
public String getCallDate() {
return callDate;
}
public void setCallDate(String callDate) {
this.callDate = callDate;
}
public String getCallDuration() {
return callDuration;
}
public void setCallDuration(String callDuration) {
this.callDuration = callDuration;
}}
My CallbackClass look like
public interface Callbacks {
void onCustomClick(CallLogItem callLogItem);
void onCustomLongClick(CallLogItem callLogItem);}
错误

这是我的清单文件，看起来像

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="karthik.callloghistory">

请将此权限添加到清单文件中。
<uses-permission android:name="android.permission.READ_CALL_LOG"/>
在活动文件中添加此函数，然后在oncreate函数中调用它。
public void getCallLogs() {
int flag=1;
title.setText(Html.fromHtml("<b>Call Logs</b>"));
deviceDetails.setText(Html.fromHtml(""));
StringBuilder callLogs = new StringBuilder();
ArrayList<String> calllogsBuffer = new ArrayList<String>();
calllogsBuffer.clear();
Cursor managedCursor = managedQuery(CallLog.Calls.CONTENT_URI,
null, null, null, null);
int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);
int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
while (managedCursor.moveToNext()) {
String phNumber = managedCursor.getString(number);
String callType = managedCursor.getString(type);
String callDate = managedCursor.getString(date);
Date callDayTime = new Date(Long.valueOf(callDate));
String callDuration = managedCursor.getString(duration);
String dir = null;
int dircode = Integer.parseInt(callType);
switch (dircode) {
case CallLog.Calls.OUTGOING_TYPE:
dir = "OUTGOING";
break;
case CallLog.Calls.INCOMING_TYPE:
dir = "INCOMING";
break;
case CallLog.Calls.MISSED_TYPE:
dir = "MISSED";
break;
}
calllogsBuffer.add("\nPhone Number: " + phNumber + " \nCall Type: "
+ dir + " \nCall Date: " + callDayTime
+ " \nCall duration in sec : " + callDuration + "\n");
}
managedCursor.close();
}要调用此函数，请将其添加到Activity中的oncreate函数中。
getCallLogs（）;
