android的Intent用法实例

1.无参数Activity跳转

1. Intent it = new Intent(Activity.Main.this, Activity2.class);
2. startActivity(it);

2.向下一个Activity传递数据（使用Bundle和Intent.putExtras）

1. Intent it = new Intent(Activity.Main.this, Activity2.class);
2. Bundle bundle=new Bundle();
3. bundle.putString("name", "This is from MainActivity!");
4. it.putExtras(bundle); // it.putExtra(“test”, "shuju”);
5. startActivity(it); // startActivityForResult(it,REQUEST_CODE);

对于数据的获取可以采用：

1. Bundle bundle=getIntent().getExtras();
2. 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）

1. Intent intent=getIntent();
2. Bundle bundle2=new Bundle();
3. bundle2.putString("name", "This is from ShowMsg!");
4. intent.putExtras(bundle2);
5. setResult(RESULT_OK, intent);

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

1. @Override
2. protected void onActivityResult(int requestCode, int resultCode, Intent data) {
3. // TODO Auto-generated method stub
4. super.onActivityResult(requestCode, resultCode, data);
5. if (requestCode==REQUEST_CODE){
6. if(resultCode==RESULT_CANCELED)
7. setTitle("cancle");
8. else if (resultCode==RESULT_OK) {
9. String temp=null;
10. Bundle bundle=data.getExtras();
11. if(bundle!=null) temp=bundle.getString("name");
12. setTitle(temp);
13. }
14. }
15. }
