主Activity

packagecom.example.moreactivity;

importandroid.os.Bundle;

importandroid.annotation.SuppressLint;

importandroid.app.Activity;

importandroid.content.ComponentName;

importandroid.content.Intent;

importandroid.view.Menu;

importandroid.view.View;

importandroid.widget.Toast;

publicclassMainActivity extendsActivity {

@Override

protectedvoidonCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

@Override

publicbooleanonCreateOptionsMenu(Menu menu) {

//Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main,menu);

returntrue;

}

publicvoidopenActivity(View v) {

Intent intent =null;

//方式一

/*

* { intent = newIntent(); //設定要啟用的元件//第一個引數：上下文

*//第二個引數：要啟用Activity的名稱intent.setClass(this,OtherActivity.class); }

*/

//方式二

/*

* { intent = newIntent(); intent.setClassName(this,

*"com.example.moreactivity.OtherActivity"); }

*/

//方式三

/*

* { intent = newIntent(); //元件的形式ComponentNamecomponent = new

*ComponentName(this, OtherActivity.class);

*intent.setComponent(component); }

*/

//方式四

/*

* { intent = newIntent(this, OtherActivity.class); }

*/

//注：方式一到四隻能啟用本應用的eActivity

//而方式五可以跨應用啟用

//方式五

{

intent = newIntent();

intent.setClassName("com.example.moreactivity","com.example.moreactivity.OtherActivity");

}

//利用意圖物件傳遞引數

/*

*intent.putExtra("name", "darren");intent.putExtra("age", 23);

*/

//批量傳遞

Bundle bundle = newBundle();

bundle.putString("name","zhengzhou");

bundle.putInt("age",100);

intent.putExtras(bundle);

//startActivity(intent);

//requestCode請求碼

//startActivityForResult(intent, requestCode);

startActivityForResult(intent,200);

}

@Override

protectedvoidonActivityResult(intrequestCode, intresultCode, Intent data) {

String result =data.getStringExtra("result");

Toast.makeText(this,result, Toast.LENGTH_LONG).show();

}

}

另一個Activty

packagecom.example.moreactivity;

importandroid.app.Activity;

importandroid.content.Intent;

importandroid.os.Bundle;

importandroid.view.View;

importandroid.widget.TextView;

publicclassOtherActivity extendsActivity {

@Override

protectedvoidonCreate(Bundle savedInstanceState) {

//TODOAuto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.otheractivity);

//得到的意圖物件就是用於啟用這個Activity的意圖物件

Intent intent =this.getIntent();

/*

* String name =intent.getStringExtra("name");

*//第二個引數表示預設值，如果取age取不到的話，就返回0int age = intent.getIntExtra("age", 0);

*/

Bundle bundle =intent.getExtras();

String name =bundle.getString("name");

intage = bundle.getInt("age");

TextView textView =(TextView) this.findViewById(R.id.label);

textView.setText("姓名："+ name + " 年齡："+ age);

}

publicvoidclose(View v) {

//resultCode結果碼錶示來自於當前Activity的那一部分資料

//setResult(resultCode, data)

Intent data = newIntent();

data.putExtra("result","new Actiovity closed");

this.setResult(30,data);

//關閉當前Avtivity

this.finish();

}

}

執行結果如圖所示：
