Android中Activity之间访问互传参数

public class MainActivity extends Activity {private static final int OTHER = 1;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}public void goOtherActivity(View v) {// 显示意图的操作/* * Intent intent = new Intent(this, OtherActivity.class); * startActivity(intent); */// 隐士意图的操作/* * Intent intent = new Intent(); intent.setAction(Intent.ACTION_CALL); * intent.setData(Uri.parse("tel:"+1235)); startActivity(intent); */// 自定义的隐士意图操作/* * Intent intent = new Intent(); * intent.setAction("www.csdn.net.hbsi");// 自定义的action * intent.addCategory("android.intent.category.DEFAULT"); *  *  * intent.setDataAndType(Uri.parse("csdn://www.csdn.net/xx"), * "image/jpeg"); // 执行意图 startActivity(intent); */// 数据传递的实现/* * Intent intent = new Intent(MainActivity.this, OtherActivity.class); *  * intent.putExtra("name", "shasha"); intent.putExtra("pass", "xxxx"); *  * startActivity(intent); */// 返回数据的获取的操作Intent intent = new Intent(MainActivity.this, OtherActivity.class);intent.putExtra("name", "shasha");intent.putExtra("pass", "xxxx");// 新打开的activity返回的数据startActivityForResult(intent, OTHER);}@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);// 请求码switch (requestCode) {// other 这个请求 的处理case OTHER:// 根据请求返回值得结果码 再进行匹配switch (resultCode) {case RESULT_OK:Toast.makeText(this, "返回的数据" + data.getStringExtra("result"),Toast.LENGTH_LONG).show();break;default:break;}break;default:break;}}}

public class OtherActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_other);// 获取数据Bundle bundle = this.getIntent().getExtras();Intent intent = this.getIntent();// Toast.makeText(this,// "名称："+bundle.get("name")+" 密码:"+bundle.get("pass"),// Toast.LENGTH_LONG).show();Toast.makeText(this,"名称：" + intent.getStringExtra("name") + " 密码:"+ intent.getStringExtra("pass"), Toast.LENGTH_LONG).show();}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {getMenuInflater().inflate(R.menu.main, menu);return true;}public void backActivity(View v) {// 显示意图的操作// Intent intent = new Intent();// intent.setClass(this, MainActivity.class);/* * intent.setClassName("com.example.lession12_activity", * "com.example.lession12_activity.MainActivity"); */// intent.setComponent(new// ComponentName("com.example.lession12_activity",// "com.example.lession12_activity.MainActivity"));// startActivity(intent);Intent intent = new Intent();intent.putExtra("result", "CSDN");OtherActivity.this.setResult(RESULT_OK, intent);OtherActivity.this.finish();// 关闭activity}}

AndroidManifest.xml中

<!-- 意图过虑器 -->           <!--  <intent-filter>                <action android:name="www.csdn.net.hbsi"/>                <data                     android:host="www.csdn.net"                    android:mimeType="image/jpeg"                    android:path="/xx"                    android:scheme="csdn"/>                <category android:name="android.intent.category.DEFAULT"/>            </intent-filter>            <intent-filter >                <action android:name="android.intent.action.MAIN"/>                <category android:name="android.intent.category.LAUNCHER"/>              </intent-filter> -->
