}
catch(Exception e)
{
e.printStackTrace();
}
}
public void googleLogin(View v)
{
Log.e("Google Button","Button Click Recognised");
signInWithGplus();

}
I have declared emailLogin method in the onClick attribute for the button. The Toast is being generated but contains nothing.

"Unfortunately, ROC has stopped." When code to retrive data from firebase(Login). NoActionBar Solution also not working

When I jump from MainActivity to AdminLog it works when adminLog.java contains the code as shown below. I have also searched for solution Like enabling noAction bar but it also doen't work. Not only for login code but it is shows same issue when I try to retrieve data from my firebase database.
package com.example.roc;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.text.TextUtils;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ProgressBar;

import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.auth.AuthResult;
import com.google.firebase.auth.FirebaseAuth;
public class adminLog extends AppCompatActivity {
EditText txtEmail, txtPassword;
ProgressBar progressBar;
Button btnSignin;
private FirebaseAuth mAuth;
private Button mgo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_admin_log);
mgo=(Button)findViewById(R.id.adminLoginBtn);
mgo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(new Intent(adminLog.this,adminWorking.class));
}
});
}
}
But it stops Working when I add login code in adminLog.java file which is also shown below.

A ListView must have the layout_height attribute not setted to wrap_content. A ListView content height is dynamic, since you don't always have the same number of cells. Thus, you need to match the parent size or have a fixed height.

App crash using intent to switch activity

It's a simple login activity but when it must switch activity, the app crash.
I tried use also the normal form pubic void onClick() {...} but it doesn't work.

the buttons in Home doesn't work yet.

Button bottone_sfida_amico = (Button)findViewById(R.id.button_sfida_amico);
Button bottone_avversario_casuale = (Button)findViewById(R.id.button_avversario_casuale);
}
}
}

When you set a method through the android:onClick attribute, your method signIn() must have a parameter View, which is the source of the event. So, declare the method as follows:
public void signIn(View view) {
...
}

can be 2 things:
1did you declare it on the manifest?
<activity android:name=".SampleActivity" android:screenOrientation="landscape"
android:label="SampleActivity"
/>
and the other reason must be the declaration of your function, when you call it for the layout it should be like this (View v) as param
public void signIn(View v) {
Intent intent = new Intent(this, Home.class);
startActivity(intent);
}

Unfortunately app has stopped ! when i try to insert some codings into the mainActivity class

When validation success,
Hope it helps!

TimePicker + CheckBox

I've got a TimePicker in my app and i want to add above it a CheckBox that if it checked the TimePicker won't work. This is my TimePicker: http://developer.android.com/guide/topics/ui/controls/pickers.html#TimePicker.
How can I do that? I want the timePicker to look the same as the example.

I will put here the entire project also for others to use it if they ever need it:
Short description: A program that let's you get the time set by user and show it in the bottom of the page, after you press Done button.Used intent to get from one activity to another.
--------Main Activity-------
package com.example.chxboxtest;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity implements OnClickListener {
private Button start_intent_button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
start_intent_button = (Button) findViewById(R.id.start_intent_button);
start_intent_button.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.start_intent_button: {
Intent intent = new Intent(this,TimePickerTest.class);
startActivity(intent);
}
break;
}
}
}
-------------Main Activity XML-----------------
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

import android.view.View.OnClickListener;
import android.widget.Button;

public class TimePickerTest extends Activity implements OnClickListener{
private CheckBox cBox;
private TimePicker tPicker;
private TextView showTime;
private Button done;
private String hour;
private String minute;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.time_picker_layout);
initButtons();
}
private void initButtons() {
tPicker = (TimePicker) findViewById(R.id.time_picker);
showTime = (TextView) findViewById(R.id.get_time);
done = (Button)findViewById(R.id.done);
cBox = (CheckBox) findViewById(R.id.time_picker_checkbox);
cBox.setOnClickListener(this);
done.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
//If check enable or disble timePicker
case R.id.time_picker_checkbox: {
if (((CheckBox) v).isChecked()) {
Toast.makeText(this, "CHECKED", Toast.LENGTH_SHORT).show();
tPicker.setEnabled(false);
} else {
Toast.makeText(this, "NOT CHECKED", Toast.LENGTH_SHORT).show();
tPicker.setEnabled(true);
}
}
break;
//If Done button pressed get time selected by user
case R.id.done:{
tPicker.clearFocus();
// re-read the values, in my case i put them in a Time object.
hour = tPicker.getCurrentHour().toString();
minute = tPicker.getCurrentMinute().toString();
if(tPicker.getCurrentMinute().intValue() < 10){
String setTimeText = hour+ " : " + "0" + minute;
showTime.setText(setTimeText);
}else{
String setTimeText = hour+ " : " + minute;
showTime.setText(setTimeText);
}
}
break;
default:
break;
}
}
}

-------------Manifest.xml-----------
**<activity

</activity>**
Dont forget to add TimePicker class as activity.
BestPracice add all xml text in strings.xml

Here's an functional example with all your requirements.
Tested and 100% functional :)
Put this in xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
>
<TextView
android:id="#+id/timer_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Check this to Cancel Alarm"
android:layout_above="#+id/time_picker"
android:layout_toRightOf="#+id/time_picker_checkbox"
/>
<CheckBox
android:id="#+id/time_picker_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/time_picker"
/>
<TimePicker
android:id="#+id/time_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
/>
And Here is your java code:
package com.example.chxboxtest;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CheckBox;
import android.widget.TimePicker;
import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener {
private CheckBox cBox;
private TimePicker tPicker;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initButtons();
}
private void initButtons() {
tPicker = (TimePicker) findViewById(R.id.time_picker);
cBox = (CheckBox) findViewById(R.id.time_picker_checkbox);
cBox.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.time_picker_checkbox: {
if (((CheckBox) v).isChecked()) {
Toast.makeText(this, "Deactivate",Toast.LENGTH_SHORT).show();
tPicker.setEnabled(false);
} else {
Toast.makeText(this, "Activate",Toast.LENGTH_SHORT).show();
tPicker.setEnabled(true);
}
}
break;
default:
break;
}
}
}
If you want this example in a custom dialog please let me know.
Cheers,
