Intent用法示例总结
Intent用法实例
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);?????? // it.putExtra(“test”, "shuju”);
startActivity(it);??????????? // startActivityForResult(it,REQUEST_CODE);
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);
??????????? }
??????? }
??? }
