A method to implement page jump and parameter transfer using intent in Android activity _android

This article is an example of an Android activity that uses intent to implement page jumps and parameter transfer methods. Share to everyone for your reference, specific as follows:

Create a new Firstavtivity.java

 package com.zhuguangwei; import android.app.Activity; import android.content.Intent;
Import Android.os.Bundle;
Import Android.view.View;
Import Android.view.View.OnClickListener;
Import Android.widget.Button;
  public class Firstactivity extends activity {private Button MyButton; /** called the activity is a.
    * * @Override public void onCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
    Setcontentview (R.layout.main);
    MyButton = (Button) Findviewbyid (R.id.mybutton); Mybutton.setonclicklistener (New Onclicklistener () {@Override public void OnClick (View v) {//TODO Au
        to-generated method Stub Intent Intent = new Intent ();
        Intent Transfer parameter Intent.putextra ("Testintent", "123");
        Intent.setclass (Firstactivity.this, Secondactivity.class);
      FirstActivity.this.startActivity (Intent);
  }
    }); }
}

Create a second Secondactivity.java

Package Com.zhuguangwei;
Import android.app.Activity;
Import android.content.Intent;
Import Android.os.Bundle;
Import Android.widget.TextView;
public class Secondactivity extends activity{
  private TextView Mytextview;
  @Override
  protected void onCreate (Bundle savedinstancestate) {
    //TODO auto-generated method stub
    Super.oncreate (savedinstancestate);
    Setcontentview (r.layout.other);
    The parameter
    Intent Intent = getintent ()
    is obtained by using the Intent object firstactivity. String value = Intent.getstringextra ("testintent");
    Mytextview = (TextView) Findviewbyid (R.id.mytextview);
    Mytextview.settext (value);
  }
}

Two activity will be registered in Androidmenifest.xml.
