Я пытаюсь добавить AdWhirl в свое приложение, но я решил начать с простого «HelloWorld», чтобы убедиться, что я знаю, что я делаю. Конечно, я не ... Я получил этот код со страницы установки AdWhirl Android SDK , но когда я пытаюсь запустить его, я получаю следующее исключение: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first. Это происходит на линии layout.addView(adWhirlLayout, layoutParams) поэтому я попытался удалить ViewView (), как подсказывает сообщение об исключении, а также removeAllViews (), но все равно я получаю эту ошибку.
Ниже приведен файл Java:
package hello.adwhirl;
import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
import android.widget.RelativeLayout.LayoutParams;
import android.widget.TextView;
import com.adwhirl.AdWhirlLayout;
import com.adwhirl.AdWhirlLayout.AdWhirlInterface;
import com.adwhirl.AdWhirlManager;
import com.adwhirl.AdWhirlTargeting;
public class HelloAdWhirl extends Activity implements AdWhirlInterface {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AdWhirlManager.setConfigExpireTimeout(1000 * 60 * 5);
AdWhirlTargeting.setAge(23);
AdWhirlTargeting.setGender(AdWhirlTargeting.Gender.MALE);
AdWhirlTargeting.setKeywords("online games gaming");
AdWhirlTargeting.setPostalCode("94123");
AdWhirlTargeting.setTestMode(false);
AdWhirlLayout adWhirlLayout = (AdWhirlLayout) findViewById(R.id.adwhirl_layout);
TextView textView = new TextView(this);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
int diWidth = 320;
int diHeight = 52;
int density = (int) getResources().getDisplayMetrics().density;
adWhirlLayout.setAdWhirlInterface(this);
adWhirlLayout.setMaxWidth((int) (diWidth * density));
adWhirlLayout.setMaxHeight((int) (diHeight * density));
layoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
textView.setText("Below AdWhirlLayout");
LinearLayout layout = (LinearLayout) findViewById(R.id.layout_main);
layout.setGravity(Gravity.CENTER_HORIZONTAL);
layout.addView(adWhirlLayout, layoutParams);
layout.addView(textView, layoutParams);
layout.invalidate();
}
public void adWhirlGeneric() {
// TODO Auto-generated method stub
System.out.println("Do stuff");
}
}
Это мой main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="@+id/layout_main">
<com.adwhirl.AdWhirlLayout
android:layout_height="wrap_content" android:layout_width="fill_parent"
android:id="@+id/adwhirl_layout"></com.adwhirl.AdWhirlLayout>
</LinearLayout>
и ошибка:
