import用法intent，android intent跳轉聲音,android intent 跳轉

轉自：http://blog.sina.com.cn/s/blog_7309444701014u2d.html

一、不需要返回值的跳轉

Intent intent=new Intent();

intent.setClass(目前的acitivy.this, 目標activity.class);

startActivity(intent);

import用法intent、二、需要返回值的跳轉

Intent intent=new Intent();

intent.setClass(發出請求的acitivy.this, 目標activity.class);

startActivityForResult(intent, 狀態值(int類型));

狀態值作為接收目標返回值的驗證。目標activity 關閉才能返回發出請求的activity

例如：

intent的用法、1、請求頁面

public class MainActivy extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

android intent？Intent intent=new Intent();

intent.setClass(MainActivy.this, ReceiveMSG.class);

startActivityForResult(intent, 0);

}

requestCode 接收返回的狀態值

resultCode ：RESULT_OK??RESULT_CANCELED 可以自己賦值，按返回鍵時，系統默認賦值為：RESULT_CANCELED

android廣播intent？protected void onActivityResult(int requestCode, int resultCode, Intent data) {

// TODO Auto-generated method stub

super.onActivityResult(requestCode, resultCode, data);

if (requestCode==0) {

if (resultCode==RESULT_OK) {

Toast.makeText(this, "Send SMS RESULT_OK", Toast.LENGTH_SHORT).show();

安卓開發intent？}else if (resultCode==RESULT_CANCELED) {

Toast.makeText(this, "result cancel", Toast.LENGTH_SHORT).show();

}else {

Toast.makeText(this, resultCode, Toast.LENGTH_SHORT).show();

}

}else {

androidhref跳轉？Toast.makeText(this, "requsetcode not 0", Toast.LENGTH_SHORT).show();

}

}

}

2、接收返回值界面

public class ReceiveMSG extends Activity{

android activity，protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

ReceiveMSG.this.setResult(RESULT_OK);

this.finish();

}

android.intent.action.MAIN，}
