我绝对尝试过我能找到的每个教程以及有关stackoverflow的任何问题，我想我错过了一些东西。
我有MainActivity和3个片段CallHistory，Contacts和Sync。
我基本上要做的是请求read_call_log;当我访问呼叫历史记录部分时写入write_call_log; read_contacts;当我访问联系人部分等时写入_contacts。我需要一些指示。
LE：忘记提及，该应用程序请求权限，但它只是崩溃了该对话框，允许我在应用程序关闭后授予/拒绝权限
在 CallHistory.java 我有这个
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_call_history, container, false);
CallLogListView = (ListView) rootView.findViewById(R.id.CallLogListView);
getCallHistory();
return rootView;
}
getCallHistory（） 驻留在 CallHistory.java 文件中
public void getCallHistory() {
if (checkSelfPermission(getActivity(),
Manifest.permission.READ_CALL_LOG)
!= PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.READ_CALL_LOG, Manifest.permission.WRITE_CALL_LOG}, READ_CALL_LOG_PERMISSION_VALUE);
} else {
m_CallLog = new ArrayList<CallLog>();
m_Cursor.moveToFirst();
try {
do {
CallLog item = new CallLog();
item.setCallLogType(m_Cursor.getString(m_Cursor.getColumnIndexOrThrow(android.provider.CallLog.Calls.TYPE)));
item.setCallLogNumber( m_Cursor.getString(m_Cursor.getColumnIndexOrThrow(android.provider.CallLog.Calls.NUMBER)));
item.setCallLogName(m_Cursor.getString(m_Cursor.getColumnIndexOrThrow(android.provider.CallLog.Calls.CACHED_NAME)));
item.setCallLogDuration(m_Cursor.getString(m_Cursor.getColumnIndexOrThrow(android.provider.CallLog.Calls.DURATION)));
m_CallLog.add(item);
} while(m_Cursor.moveToNext());
} finally {
if (!m_Cursor.isClosed()) {
m_Cursor.close();
}
prefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
m_CallLogAdapter = new CallLogAdapter(getActivity(), R.layout.row, m_CallLog);
CallLogListView.setAdapter(m_CallLogAdapter);
CallLogListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView adapterView, View view, int position, long id) {
CharSequence colors[] = new CharSequence[] {
"Send contact info",
"Send directions",
"Save contact"
};
phoneNumber = ((TextView) view.findViewById(R.id.toptext)).getText().toString();
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Action for " + phoneNumber);
builder.setItems(colors, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
AlertDialog.Builder message = new AlertDialog.Builder(getActivity());
if(which == 0)
{
Toast.makeText(getContext(), "Sending contact details to " + phoneNumber + " ...", Toast.LENGTH_SHORT).show();
sendSms(phoneNumber, prefs.getString("edit_text_preference_1", getText(R.string.default_contact_sms).toString()));
}
else if(which == 1)
{
Toast.makeText(getContext(), "Sending directions to " + phoneNumber + " ...", Toast.LENGTH_SHORT).show();
sendSms(phoneNumber, prefs.getString("edit_text_preference_2", getText(R.string.default_directions_sms).toString()));
}
else if(which == 2)
{
if(contactExists(getContext(), phoneNumber)) {
Toast.makeText(getContext(), "Contact already exists. Cheers!", Toast.LENGTH_SHORT).show();
} else {
Intent saveContactIntent = new Intent(getActivity(), ContactsAdd.class);
saveContactIntent.putExtra("phoneNumber", phoneNumber);
startActivity(saveContactIntent);
}
}
}
});
builder.show();
}
});
}
}
}
