Activity几种跳转

显式跳转：

Intent intent = new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(intent);

Intent intent1 = new Intent();
ComponentName name = new ComponentName("com.bysj.yrj","com.bysj.yrj.RegisterActivity");
intent.setComponent(name);
startActivity(intent1);

Intent intent2 = new Intent();
intent1.setClass(LoginActivity.this,RegisterActivity.class);
startActivity(intent2);

隐式跳转：

AndroidManifest.xml

<activity
    android:name=".RegisterActivity"
    android:label="@string/title_activity_register">
    <intent-filter>
        <action android:name="action.RegisterActivity(启动的名字)" />
        <category android:name="android.intent.category.DEFAULT(默认)" />
    </intent-filter>
</activity>

Intent intent3 = new Intent();
intent3.setAction("action.RegisterActivity");
startActivity(intent3);

Intent intent4 = new Intent("action.RegisterActivity");
startActivity(intent4);
