Question

我的要求是一个活动正在调用另一个活动。当我从父活动的销售路线列表中单击单选按钮时，对话框（称为子）将会出现。它包含表单。完成小型工作后，它会转到以前的位置（需要继续工作）。

我这样做了：

Androidmanifest.xml

 <activity android:theme="@android:style/Theme.Light.Panel" android:name=".SalesRouteDevitionActivity"
              android:label="Sales Route Diviation">
    </activity>

然后我的销售路线java部分列表是：

 @Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    Object o = this.getListAdapter().getItem(position);
    keyword = o.toString();
    positions = position;

    if(position != 0 ){
        Bundle bundle = new Bundle();

        Intent showContent = new Intent(v.getContext(),SalesRouteDevitionActivity.class);
        int postion = position;
        String aString = Integer.toString(postion);
        bundle.putString("positon", aString);
        showContent.putExtras(bundle);
        startActivityForResult(showContent, 2);


    }else{

        Intent intent = new Intent(SalesRouteActivity.this, ListRetailerActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("RouteName", keyword);
        intent.putExtras(bundle);
        View view = SalesActivityGroup.group.getLocalActivityManager().startActivity("", intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();  
        SalesActivityGroup.group.replaceView(view);
    }


}

  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      if( resultCode==Activity.RESULT_OK){
          Toast.makeText(this, "Reason has been successfully.", Toast.LENGTH_LONG).show();
          if(resultCode==RESULT_OK)
              Toast.makeText(this, "Reason has been successfully.", Toast.LENGTH_LONG).show();
         else
              Toast.makeText(this, "Fail", Toast.LENGTH_LONG).show();
      }

 // super.onActivityResult(requestCode, resultCode, data);
  }

我的孩子活动是：

      public class SalesRouteDevitionActivity extends Activity {
private String array_spinner[];
String param1 = "";
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.route_diviation_popup);
    array_spinner=new String[2];
    array_spinner[0]="Rain";
    array_spinner[1]="Floods";

    Spinner s = (Spinner) findViewById(R.id.spinner1);
    ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_dropdown_item, array_spinner);
    s.setAdapter(adapter);
    Button button = (Button) findViewById(R.id.submit);

     button.setOnClickListener(new OnClickListener() {
         public void onClick(View v) {
             Intent intent= new Intent(getApplicationContext(),SalesRouteActivity.class);
             Log.i("*********" ," --- " +getParent());
             if (getParent() == null) {
                 setResult(RESULT_OK, intent);
             } else {
                 getParent().setResult(RESULT_OK, intent);
            }
             finish();
         }
     });
}

完成弹出式活动后，我的问题是，它没有转到onActivityResult()方法

我怀疑，如果主题为@android:style/Theme.Dialog，那么我们可以使用onActivityResult();

请帮帮我......

我花了一天多......可能是小问题......

Answer 1

您没有从intent传递任何值，因此请尝试删除intent并使用如下：

的setResult（RESULT_OK）;

Answer 2

试试这段代码..

     button.setOnClickListener(new OnClickListener() {
             public void onClick(View v) {
                 Intent intent= SalesRouteDevitionActivity.this.getIntent();
                 Log.i("*********" ," --- " +getParent());
                 if (getParent() == null) {
                     SalesRouteDevitionActivity.this.setResult(SalesRouteDevitionActivity.RESULT_OK, intent);
                 } else {
SalesRouteDevitionActivity.this.getParent().setResult(SalesRouteDevitionActivity.RESULT_OK, intent);
                }
                 finish();
             }
         });

Answer 3

getParent().setResult(RESULT_OK, intent);

此行为might be faluty，因为getParent()返回调用活动，实际上如果从另一个活动X调用SalesRouteDevitionActivity则返回THAT X活动。但由于该活动在OnPause()并且正在侦听结果，因此您无法同时从同一X活动设置结果，而是从SalesRouteDevitionActivity设置结果，然后完成它。像

SalesRouteDevitionActivity.this.setResult(RESULT_OK, SalesRouteDevitionActivity.this.getIntent());
SalesRouteDevitionActivity.this.finish();

还要重写onActvityResult()，然后测试请求代码，然后测试结果代码......

   @Override
      protected void onActivityResult(int requestCode, int resultCode, Intent data) {
          Log.i("TEST ON RESULT", "SUCCESS");
          if( requestCode==2){

              if(resultCode==RESULT_OK)
                  Toast.makeText(this, "Reason has been successfully.", Toast.LENGTH_LONG).show();
             else
                  Toast.makeText(this, "Fail", Toast.LENGTH_LONG).show();
          }

我已通过此链接完成此操作。

startActivityForResult from ActivityGroup? 。它对ActivityGroup的startActivityForResult非常有帮助

Answer 5

我遇到了类似的问题。我有一个ActivityGroup管理子活动。其中一个子活动称为类似的外部意图（我的应用程序外部）。它从未在启动它的子活动中调用onActivityResult。

我终于弄清楚/记得这个问题是因为Android只允许嵌套的子活动层......即子活动不能嵌套子活动。要解决这个问题：

call getParent().startActivityForResult() from your sub-activity
your parent (the activitygroup) will be able to handle the onActivityResult. So I created a subclass of ActivityGroup and handled this onActivityResult.
You can re-route that result back to the sub-activity if you need to. Just get the current activity by getLocalActivityManager().getCurrentActivity() . My sub-activities inherit from a custom activity so I added a handleActivityResult(requestCode, resultCode, data) in that subclass for the ActivityGroup to call.
