Calling different layers from the same class
- by khalid
Hi, I am here to seek some help with my code which i am facing a dead end road with. I'm trying to pass values from screen1.java using Intent to screen2.java. Passing the values is fine and I managed to get through it; however, when I check using if statement the program crash down. Here are my files, plzzzzzzzzzzz help
screen1.java
package test.android;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class screen1 extends Activity
{
static String strKey = "Hello";
static final String strValue = "Hello";
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.screen1);
//** button A
Button A = (Button) findViewById(R.id.btnClickA);
A.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Intent i = new Intent(screen1.this, screen2.class);
strKey = "NAME";
i.setClassName("packageName", "packageName.IntentClass");
String term = "Hello";
i.putExtra("packageName.term", term);
//i.putExtra(strKey, strValue);
startActivity(i);
}
});
//**
//** button B
Button B = (Button) findViewById(R.id.btnClickB);
B.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Intent i = new Intent(screen1.this, screen3.class);
startActivity(i);
}
});
//**
}
}
screen2.java
package test.android;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class screen2 extends Activity
{
public void onCreate(Bundle icicle)
{
Bundle extras = getIntent().getExtras();
String term = extras.getString("packageName.term");
System.out.println("--- Name is -->"+ term);
if(term.equalsIgnoreCase("Hello") || term.equalsIgnoreCase("Name")){
super.onCreate(icicle);
setContentView(R.layout.screen3);
Button b = (Button) findViewById(R.id.btnClick3);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
setResult(RESULT_OK);
finish();
}
});
} else {
super.onCreate(icicle);
setContentView(R.layout.screen2);
Button b = (Button) findViewById(R.id.btnClick2);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
setResult(RESULT_OK);
finish();
}
});
}
// DOES NOT WORK !!!!!!!!!
System.out.println("--- Name is --"+ term);
}
}
Layouts:
screen1.xml
screen2.xml
screen3.xml
AndroidManifest.xml
<activity android:name="screen1"
android:label="SCREEN 1">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="screen2"
android:label="SCREEN 2">
</activity>
<activity android:name="screen3"
android:label="SCREEN 3">
</activity>
=====
The error is caused by these lines of code in screen2.java:
if(term.equalsIgnoreCase("Hello") || term.equalsIgnoreCase("Name")){
super.onCreate(icicle);
setContentView(R.layout.screen3);
Button b = (Button) findViewById(R.id.btnClick3);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
setResult(RESULT_OK);
finish();
}
});
}
else {
super.onCreate(icicle);
setContentView(R.layout.screen2);
Button b = (Button) findViewById(R.id.btnClick2);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
setResult(RESULT_OK);
finish();
}
});
}
**notice if I get rid of the entire IF statement and go with only the ELSE the program works fine.
