I tried to display User Input from my main activity to my second activity, but when I typed in and click the send button on the main activity the whole app just crashes. Please help!
crash solved! Thanks a lot!
However, I can't get the message to display on the second activity.

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);
}
}

Android ListView not wrapping text

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.

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;

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);
}

Change TextView when item is clicked on a ListAdapter?

I have two classes and a XML. The first one creates an ListApter full of cocktail names like bloody mary,margarita, ect. The second class is set up so I can change the TextView and an Image displayed in the XML. I'm having difficulty trying to pass the item that I'v pressed in the ListAdapter into the CocktailDetail class to change the values of the TextView and the Image. Can anybody help? It runs but opens Bloody mary for every item selected in the list.

In Menu class, you are passing hard coded string :
ourIntent.putExtra("cocktail_name",**"bloodymary"**);
Change this to the value retrieved from the ListView :
String selectedFromList =(String) (l.getItemAtPosition(position));
ourIntent.putExtra("cocktail_name",selectedFromList);
Also in Cocktail Class, OnCreate, again you are setting text to hardcoded string. Using Bundle, retrieve the value and then setText;
Bundle bundle = getIntent().getExtras();
//Extract the data…
String name = bundle.getString(“cocktail_name”);
TextView t1 = (TextView)findViewById(R.id.textCocktailName);
t1.setText(name);

Try this in Menu activity:
// React to user clicks on item
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parentAdapter, View view, int position,
long id) {
// here you get the Item selected using position
Intent i = new Intent(MenuActivity.this, CocktailDetails.class);
i.putExtra("title", your_title_cocktail);
startActivity(i);
}
});
in the DetailActivity
protected void onCreate(Bundle savedInstanceState) {
Intent i = getIntent();
---
}
give a look here and here.

layout elements not showing up

I have two activities and the first is generating properly however the second is not. only the first element in the xml file will show up. here is my xml file:

if(textToChange.equals(R.string.originalText)){
textToChange.setText(R.string.newText);
} else {
textToChange.setText(R.string.originalText);
}
}
}
has anyone else seen this problem? or know of a way to fix it?

Try to add android:orientation="vertical" to your LinearLayout

replace
Intent i = new Intent(this, activityTest.class);
by
Intent i = new Intent().setClass(this, activityTest.class);
