I want to start an activity, so I picked this Class way. I know I can do it easily by passing ACTION NAME directly in intent constructor but I am learning android so I trying to learn new ways. I started another activity with the same code in other class and it working there but here it is giving the following error. I think it has to some thing with THREAD class.
The error is:
The constructor Intent(new Thread(){}, Class) is undefined.
How can I solve this? Here is the code:
package com.umer.practice2;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class SplashScreen extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
Thread timer= new Thread()
{
public void run()
{
try
{
sleep(5000);
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
Class ourclass = Class.forName("com.umer.practice2.StartingPoint");
Intent myintent= new Intent(this,ourclass); // error
startActivity(myintent);
}
}
};
timer.start();
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}
Here is the layout of the class activity which is giving force close error.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="hint"
android:id="@+id/fdisp"
/>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="How many times you eat in a day"
android:gravity="center"
android:id="@+id/but3"
/>
</LinearLayout>
and here is the code of the class itself
package com.umer.practice2;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MyClass extends Activity{
Button b3;
TextView disp;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
b3= (Button) findViewById(R.id.but3);
disp= (TextView) findViewById(R.id.fdisp);
b3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
disp.setText("It depends ");
}
});
}
}
Just replace the intent creation by:
Intent myintent= new Intent(SplashScreen.this, StartingPoint.class);
Otherwise, this
refers to the enclosing Thread
class
you can call as given below
startActivity(new Intent(SplashScreen.class, StartingPoint.class);
It will work. Try it.
