隐式Intent在Activity中调用Activity

如果你不知道那个APP的Activity,但是知道包名(package name),那么可以使用如下的方法:
Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
startActivity(LaunchIntent);
如果APP之间有合作关系,可以获得合作APP的清单文件(manifest),那么可以从该文件中获知package/activity,
可使用如下的方法来启动该APP特定活动界面:
Intent intent = new Intent(Intent.ACTION_MAIN); intent.setComponent(new ComponentName("com.package.address","com.package.address.MainActivity")); startActivity(intent);
如果要在启动APP时传递参数,可以在意图(Intent)中设置:
intent.putExtra("firstKeyName","FirstKeyValue");
intent.putExtra("secondKeyName","SecondKeyValue");
