显式Intent的实现方式

//方式1: 
Intent intent = new Intent(context,目标类);
startActivity(intent);

//方式2
Intent intent = new Intent( );
ComponentName cn = new ComponentName(context,目标类);
intent.setComponent(cn);
startActivity(intent);

隐式Intent的实现方式

//1：action
public final static String CRAZYIT_ACTION ="org.crazyit.intent.action.CRAZYIT_ACTION";
Intent intent = new Intent();
intent.setAction(MainActivity.CRAZYIT_ACTION);
startActivity(intent);


//2：category
final static String CRAZYIT_CATEGORY = "org.crazyit.intent.category.CRAZYIT_CATEGORY";
Intent intent = new Intent();
intent.addCategory(MainActivity.CRAZYIT_CATEGORY);
startActivity(intent);


//3：data
Intent intent = new Intent();
intent.setDataAndType(Uri.parse("lee://www.fkjava.org:8888/mypath"), "abc/xyz");


//4：type
//未指定Data属性，Type才会发挥作用



<intent-filter>
    <!-- 指定该Activity能响应action为指定字符串的Intent -->
    <action android:name="org.crazyit.intent.action.CRAZYIT_ACTION" />
    <!-- 指定该Activity能响应category为指定字符串的Intent -->
    <category android:name="org.crazyit.intent.category.CRAZYIT_CATEGORY" />
    <!-- 指定该Activity能响应category为android.intent.category.DEFAULT的Intent -->
    <category android:name="android.intent.category.DEFAULT" />

    <!-- 需要Intent的Data属性的scheme是lee，且host是www.fkjava.orgport是8888，且path是/mypath且type是abc/xyz，才可启动该Activity -->
    <data android:scheme="lee"
        android:host="www.fkjava.org"
        android:port="8888"
        android:path="/mypath"
        android:mimeType="abc/xyz"/>

</intent-filter>

Extras属性

Bundle data=new Bundle();       
data.putString("name", sTemp1);
data.putString("pwd", sTemp2);       
Intent intent=new Intent(LoginCallActivity.this,DataShowActivity.class);    

intent.putExtras(data);

//intent默认Bundle
//intent.putExtras("name",sTemp1);
//intent.putExtras("pwd",sTemp2);
