在开发Android应用时,有时为了收益会增加一些广告。但是广告不断的滚动显示,又很烦人,降低用户体验,所以就需要增加一个关闭的按钮来隐藏或者关闭广告。有的应用是直接将关闭广告的功能做到了设置界面里边,但有的是在广告上增加了一个按钮。这里以迷你广告为例。
万普的迷你广告是一个LinearLayout,我开始尝试着在上面直接添加一个关闭按钮,然后设置相应的布局参数,但是效果不理想。后来改用RelativeLayout作为父容器,将迷你广告的LinearLayout和关闭按钮一同放进去。下面是实现的代码。
Waps.java
package com.sparkle.ad;
import android.app.Activity;
import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.graphics.Color;
import android.opengl.Visibility;
import android.text.Layout;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.FrameLayout;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
import android.widget.RelativeLayout;
import cn.waps.AppConnect;
import com.sparkle.qrcode.R;
public class Waps {
private static String _appId = "";
private static String _advertismentPlatform = "default";
private static AppConnect _appConnect = null;
private static void GetChannelInfo(Activity activity) {
ApplicationInfo appInfo = null;
try {
appInfo = activity.getPackageManager().getApplicationInfo(
activity.getPackageName(), PackageManager.GET_META_DATA);
} catch (NameNotFoundException e) {
e.printStackTrace();
}
_appId = appInfo.metaData.getString("APP_ID");
_advertismentPlatform = appInfo.metaData.getString("APP_PID");
}
public static void Start(Activity activity) {
GetChannelInfo(activity);
_appConnect = AppConnect.getInstance(_appId, _advertismentPlatform,
activity);
if (_appConnect == null) {
return;
}
_appConnect.setAdBackColor(Color.argb(50, 120, 240, 120));
_appConnect.setAdForeColor(Color.YELLOW);
LinearLayout miniLayout = GenerateMiniLinearLayout(activity);
_appConnect.showMiniAd(activity, miniLayout, 10);
}
private static LinearLayout GenerateMiniLinearLayout(Activity activity) {
final RelativeLayout relativeLayout = new RelativeLayout(activity);
LinearLayout miniLayout = new LinearLayout(activity);
ImageView close_imageView = new ImageView(activity);
close_imageView.setBackgroundResource(R.drawable.close);
close_imageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
relativeLayout.setVisibility(View.GONE);
}
});
RelativeLayout.LayoutParams closeParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
closeParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
close_imageView.setLayoutParams(closeParams);
relativeLayout.addView(miniLayout);
relativeLayout.addView(close_imageView);
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
layoutParams.gravity=Gravity.BOTTOM;
activity.addContentView(relativeLayout, layoutParams);
return miniLayout;
}
public static void Close(Context context) {
AppConnect.getInstance(context).close();
}
}
注:
(1)、APP_ID和APP_PID在AndroidManifest.xml中配置。
(2)、Start函数用来启动广告。
(3)、Close函数用来关闭广告。
(4)、GenerateMiniLinearLayout函数中生成了RelativeLayout的相对布局。在RelativeLayout中,添入迷你广告miniLayout和关闭按钮close_imageView。close_imageView设置背景图和点击事件。点击事件中,只是将广告隐藏了,如果有需要可以直接关闭。
要点:
(1)、为了能将close_imageView设置到右侧,需要使用RelativeLayout.LayoutParams(不是LinearLayout.LayoutParams,我开始用的是这个,然后用gravity,怎么都达不到效果),再使用addRuler来设置ALIGN_PARENT_RIGHT。
(2)、在addContentView中,需要布局RelativeLayout。使用FrameLayout.LayoutParams来布局(注意一定要用这个,RelativeLayout.LayoutParams和LinearLayout.LayoutParams都用过,达不到效果),设置gravity即可。
