intent系统跳转action

1.直接跳转到goole原生的sms进行短信的编辑：
alternateIntent = new Intent(Intent.ACTION_SENDTO,
Uri.fromParts(ContactsUtils.SCHEME_SMSTO, phone.getNumber(), null));//跳转至短信并自动填充收件人
//alternateIntent.setComponent(new ComponentName("com.android.mms", "com.android.mms.ui.ComposeMessageActivity"));//如果要跳转到指定的短信模块，加上此句即设置跳转

其中跳转方式包含：
ComponentName com = new ComponentName(MainActivity.this,MyActivity.class);//first
ComponentName com = new ComponentName
("com.example.testcomponent","com.example.testcomponent.MyActivity");//second

 button.setOnClickListener(new Button.OnClickListener() {
 @Override
 public void onClick(View arg0) {
 // TODO Auto-generated method stub
 Intent intent = new Intent();
 ComponentName com = new ComponentName(
 "com.example.testcomponent",
 "com.example.testcomponent.MyActivity");
 intent.setComponent(com);
 String s = "This is a Test.";
 intent.putExtra("id", s);
 startActivity(intent);
 }
 });

Intent intent = getIntent();
 String str = intent.getStringExtra("id");
 ComponentName com = intent.getComponent();
 String pkgName = com.getPackageName();
 String className = com.getClassName();
 text.setText(str + "\n" + pkgName + "\n" + className);
 

2.跳转到google短信中并携带内容：

     String defaultSmsPackageName = Telephony.Sms.getDefaultSmsPackage(mContext);
     Intent intent = new Intent(Intent.ACTION_SEND);//根据sdk版本，文献这查说是4.4之后用此action,
     intent.setType("text/plain");//设置携带内容的格式
     intent.putExtra(Intent.EXTRA_TEXT, localSmsContactComposer.getData());
     if (defaultSmsPackageName != null){
         intent.setPackage(defaultSmsPackageName);//指定报名后可以直接跳转到默认，而不是出现多项选择
     }
    try {
        startActivity(intent);
        return;
    } catch (ActivityNotFoundException localActivityNotFoundException) {
        Log.e(TAG, "No activity found for intent: " + intent);
    }
