                    @Override
                    public void onClick(DialogInterface dialog, int id) {
                        // Your code when user clicked on OK
                        // You can write the code to save the selected item here

                    }
                })
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int id) {
                                // Your code when user clicked on Cancel

                            }
                        });
        AlertDialog dialog = builder.create();
        dialog = builder.create();// AlertDialog dialog; create like this
                                    // outside onClick
        dialog.show();
    }

    protected void onChangeSelectedSelection() {
        StringBuilder stringBuilder = new StringBuilder();
        for (CharSequence selection : selectedInterests)
            stringBuilder.append(selection + ",");

        // filterButton.setText(stringBuilder.toString());
        String input = selectedInterests.toString();
        System.out.println(input);
        if (input.contains("Date")) {



             Intent intent = new Intent();

             intent.setClassName("com.nous.demoexample", "com.nous.demoexample.Dateactvity");

             startActivity(intent);



        }

    }

}

第二类:

public class Dateactvity extends  Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.date);


  }

 }

表示文件代码:

<application android:name=".Dateactvity"></application>

此错误即将到来.

09-12 10:58:34.253: E/AndroidRuntime(275): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.nous.demoexample/com.nous.demoexample.Dateactvity}; have you declared this activity in your AndroidManifest.xml?

推荐答案

您需要声明为...

<activity android:name="com.nous.demoexample.Dateactvity"></activity>

并使用类似...的意图

And use intent like...

 Intent intent = new Intent(MultiColumnActivity.this,Dateactvity.class);
 startActivity(intent);
