I'm working on an app where whatevever the user speaks on the phone gets added to the listview(up to this is working fine) and on clicking that item on that list view,send that over to the parse server.
This is my class called Speech
`package com.example.projecta;
import java.util.ArrayList;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import com.parse.Parse;
import com.parse.ParseAnalytics;
import com.parse.ParseObject;
public class Speech extends Activity implements OnClickListener {
ListView viewlist;
static final int check = 1111;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.speech);
Parse.initialize(this, "JnmLmnvOjxvRgBMGPl4XzOzvoqPPY7KGG2cqiExL", "8ejsJCanB26YYB6Io3jKov5wcwuajcB1zjRPUyMs");
ParseObject.registerSubclass(Storedata.class);
ParseAnalytics.trackAppOpened(getIntent());
viewlist = (ListView)findViewById(R.id.speechview);
Button b = (Button)findViewById(R.id.speechb);
b.setOnClickListener(this);
}
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent in = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
in.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
in.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak Louder");
startActivityForResult(in, check);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if (requestCode == check && resultCode == RESULT_OK){
ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
viewlist.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, results));
}
super.onActivityResult(requestCode, resultCode, data);
}
public void createStoredata(View v) {
Storedata st = new Storedata();
st.setDescription(viewlist.toString());
st.saveEventually();
}
}
`
This is my store data class
package com.example.projecta;
import com.parse.ParseObject;
public class Storedata extends ParseObject{
public Storedata(){
}
public void setDescription(String description){
put("description", description);
}
{
}
}
I really need help with this thanks.
You need to add a listener to your listview itself to click the items
viewlist.setClickable(true);
viewlist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
//perform action with your item
}
});

public static void addFriend(String name, String nickname, String imgpath){
Friend friend = new Friend(name,nickname,imgpath);
friendlist.add(friend);
}
public int getSize(){
return friendlist.size();
}
public Friend getFriend(int position){
return friendlist.get(position);
}
}
Where the RecyclerView is handled adapterName.notifyDataSetChanged (); you need to run.
In your case, the data is collected statically. The place where the data is processed is a different Activity.
After switching to the new screen and adding data, you will need to update your adapter in onResume if you want the relevant data to appear when you come back. Recyclerview will appear blank since there is no data in its initial state.
#Override
public void onResume() {
super.onResume();
adapter.notifyDataSetChanged();
}
I'm making a simple place picker program in android. I want to save some text when user choose a point on map with place picker. And the problem is when I click on button the place picker opens too long and variable which is responsible for place can't keep up change and dialog that responses for enter text never opens. I think, maybe problem is with threads, isn't it?

Please help me, what could go wrong?
Your problem is that the Place Picker communicates with your main activity asynchronously, so you're opening your dialog before it returns. Try waiting until Place Picker has returned before opening the dialog like so:
.
.
.
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.AddEventButton:
place = null;
callPlacePicker();
break;
}
}
.
.
.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_PICKER_REQUEST) {
if (resultCode == RESULT_OK) {
place = PlacePicker.getPlace(this, data);
openDialog();
}
}
}

PS: I'm very new to coding, and I'm using someone else project
Make sure that you have added permissions for Bluetooth in your AndroidManifest.xml file as follows :
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
And you need to check if bluetooth is enabled, if not, request to enable it.
So, instead of checking (mBluetoothAdapter.isEnabled()) , you need to check not condition as follows and need to call Bluetooth enable Intent:
(!mBluetoothAdapter.isEnabled()).
Also, you need to add return statement if you get the instance of BluetoothAdapter as null. See the code below :
if (mBluetoothAdapter == null) {
Log.d(TAG, "enableDisableBT: Does not have BT capabilities.");
return; // missing statement
}
I hope this will help you.

Are you sure if the birthday date exists on Facebook profile as well? or they may have set to privacy.

You need to start your second activity with the flag that you are waiting for a result, so instead of startActivity you need to make use of startActivityForResult.
If you need a little bit more information take a look at this tutorial it should cover all you need to get things working.
