I have an application which I am developing. I need to password protect it, i.e. a password needs to be entered before allowing access to the main content.
Password can be stored locally in the Java file.

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!

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);
}
}
This is my java class, MainActivity.java.
Basically I'm trying to create a button performing addition on variable i. Everything seems to be correct as far as I learnt until now. I am getting an error message on my emulator saying:
unfortunately myfirstandroidapp stopped working.
Code:
package com.example.android.myfirstandroidapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;
import android.util.Log;
public class MainActivity extends AppCompatActivity {
int i = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Button button = (Button) findViewById(R.id.addButton);
final TextView txtView = (TextView) findViewById(R.id.textView);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
i++;
txtView.setText("i value is:"+i);
}
});
setContentView(R.layout.activity_main);
}
}
This is my layout.xml

You need to call setContentView() before initializing any View.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.addButton);
final TextView txtView = (TextView) findViewById(R.id.textView);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
i++;
txtView.setText("i value is:"+i);
}
});
}

Tried: if i run projetc with below codes it works fine
public class MainActivity extends Activity {

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); }
}
and if i insert anycode after the
setContentView(R.layout.activity_main);
like this
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

username=(EditText) findViewById(R.id.EditText1);
password=(EditText) findViewById(R.id.EditText2);
final EditText result=(EditText) findViewById(R.id.EditText3);
Button login=(Button) findViewById(R.id.button1); }
}
it makes Unfortunately app has stopped problem please answer me as soon as possible

When app starts,
When validation fails,
When validation success,
Hope it helps!
I have a 2 activities with edittexts on them the first activity work fine but the second activity's EditText is focused but I can't edit it nor can I click the button on it.
Also everything works in the emulator but not when I install it on the device. (The keyboard popup also does not come up in the second activity where as it does in the first activity)

I just figured to re-create the app. I dont think it is a wise decision to copy the raw files to another directory and use that.
i need to copy the text field data to another onclick
below is my activitymain,xml of my app

EditText editText1 = (EditText) findViewById(R.id.editText1);
EditText editText2 = (EditText) findViewById(R.id.editText2);
Button b= (Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
String data = editText1.getText().toString();
editText2.setText(data);
});
