App crash using intent to switch activity

App crash using intent to switch activity - android

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.
Login.java

Username=(EditText)findViewById(R.id.nickname);
Password=(EditText)findViewById(R.id.password);
String a = Username.getText().toString();
String b = Password.getText().toString();
player.inserisciCredenziali(a,b); //insert into a player class
//username and password
signIn();
}
public void signIn() {
Intent intent = new Intent(this, Home.class);
startActivity(intent);

Home.java
the buttons in Home doesn't work yet.
package com.example.corrado_mattia_danny.face_offbrains;
import android.app.Activity;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;

import android.view.View;
import android.widget.Button;
public class Home extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
Intent intent = getIntent();
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, 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;

You are passing int, but receive it in String, so your app crashed.
MainActivity
int message = R.string.UserInput;
Intent sendMessage = new Intent(MainActivity.this, DisplayMessageActivity.class);
sendMessage.putExtra("UserInput", message);
DisplayMessageActivity
Bundle Extra = getIntent().getExtras();
String textView = Extra.getString("UserInput");
You should also add
intent.putExtra("UserInput", message);
into launchActivity method.
Solution 1
Change String textView = Extra.getString("UserInput"); to int textView= Extra.getIntExtra("UserInput", 0);
Solution 2
To send the message to your second Activity, you need to use intent inside your MainActivity button click. Modify your code as below.
package com.example.dell_inspiron.sendmessage;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import static android.R.id.message;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String message = getResources().getString(R.string.UserInput);
final Button send = (Button) findViewById(R.id.send);
send.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
Intent sendMessage = new Intent(MainActivity.this,DisplayMessageActivity.class);
sendMessage.putExtra("UserInput", message);
startActivity(sendMessage);
}
});
}
}
Solution 3
This line look wrong to me
final String message = getResources().getString(R.string.UserInput);
If you want to get the editText string, this is the way to go
EditText input = (EditText)findViewById(R.id.UserInput); // declare your editText
final String message = input.getText().toString(); // get your input type

You mentioned that you are getting the user input from the MainActivity but i don't see anything like that in your code but you can do the below to pass some value from one activity to another...
Change your second activity like this
Bundle Extra = getIntent().getExtras();
String textView = Extra.getString("UserInput");
to
Intent Extra = getIntent();
String textView = Extra.getStringExtra("UserInput");
and change your MainActivity like this
int message = R.string.UserInput;
to
String message= getResources().getString(R.string.UserInput);
and
final Button send = (Button) findViewById(R.id.send);
send.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
launchActivity();
}
});
to
Button send = (Button) findViewById(R.id.send);
send.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
startActivity(sendMessage);
}
});

There is issue with your second Activity.You are passing int value in Intents but trying to get String value.
Change it as below:
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;
public class DisplayMessageActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_message);
Bundle Extra = getIntent().getExtras();
int textView = Extra.getInt("UserInput");
TextView UserInput = (TextView) findViewById(R.id.UserInput2);
UserInput.setText(textView);
final Button button = (Button) findViewById(R.id.button2);
button.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
launchActivity();
}
});
}
private void launchActivity() {
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}
}

Make EditText callable across Activitys

I'm trying to call an EditText from one activity to another but when i do my app crashes.
I've tried using the addPreferencesFromResource method using 'import android.preference.PreferenceActivity' and import android.preference.PreferenceFragment' but the 'addPreferencesFromResource' stays red.
How can I make it callable ?
