Intent使用总结（传递,打开Activity方式）

1.无参数Activity跳转
Intent it = new Intent(Activity.Main.this, Activity2.class);

startActivity(it);

2.向下一个Activity传递数据（使用Bundle和Intent.putExtras）
Intent it = new Intent(Activity.Main.this, Activity2.class);

Bundle bundle=new Bundle();

bundle.putString("name", "This is from MainActivity!");

it.putExtras(bundle);

startActivity(it);

对于数据的获取可以采用：

Bundle bundle=getIntent().getExtras();

String name=bundle.getString("name");

3.向上一个Activity返回结果（使用setResult，针对startActivityForResult(it,REQUEST_CODE)启动的Activity）
Intent intent=getIntent();

Bundle bundle2=new Bundle();

bundle2.putString("name", "This is from ShowMsg!");

intent.putExtras(bundle2);

setResult(RESULT_OK, intent);

4.回调上一个Activity的结果处理函数（onActivityResult）
@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

// TODO Auto-generated method stub

super.onActivityResult(requestCode, resultCode, data);

if (requestCode==REQUEST_CODE){

if(resultCode==RESULT_CANCELED)

setTitle("cancle");

else if (resultCode==RESULT_OK) {

String temp=null;

Bundle bundle=data.getExtras();

if(bundle!=null) temp=bundle.getString("name");

setTitle(temp);

}

}

}
