将param传递给java android类

Question

这是我要去的班级

public class AxxessCCPAccountDetails extends Activity {

public AxxessCCPAccountDetails(String username) {

}
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.accountdetails);
}

}

这是我传递的代码

lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> parent, View view,
          int position, long id) {
        // When clicked, show a toast with the TextView text
        Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
            Toast.LENGTH_SHORT).show();

        Intent myIntent = new Intent(view.getContext(), AxxessCCPAccountList.class);
        startActivityForResult(myIntent, 0);
      }
    });

我需要将用户名传递给一个类.我如何将该参数传递给该类,然后激活链接到视图的活动(类).

谢谢

Answer 1

用Intent.您不应该为Activity该类创建自己的构造函数.

这是一个简短的例子:

Intent myIntent = new Intent(view.getContext(), AxxessCCPAccountList.class);
myIntent.putExtra("username", userName);
myIntent.putExtra("pass", pass);

然后,在你的AxxessCCPAccountList.onCreate方法中:

String userName = this.getIntent().getStringExtra("username");
String pass = this.getIntent.getStringExtra("pass");
