将 Admob 广告添加到 Java 文件而不是 Xml

Question

我在添加 Admob 广告时遇到问题。首先，我正在开发一款不使用 xml 布局的游戏。我只使用Java。 在 Google 的说明中，它会查找线性布局 ID。 任何帮助都会很棒。 这是我在 Manifest 中声明的主要活动 java 文件的代码：

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.widget.LinearLayout;
import com.google.android.gms.ads.*;

public class CrazyEightsActivity extends Activity {
/** Called when the activity is first created. */
private AdView adView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    TitleView tView = new TitleView(this);
    tView.setKeepScreenOn(true);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                         WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.activity_main);
 // Create the adView.
    adView = new AdView(this);
    adView.setAdUnitId("ca-app-pub-6705249916909813/9815575080");
    adView.setAdSize(AdSize.BANNER);

    // Lookup your LinearLayout assuming it's been given
    // the attribute android:id="@+id/mainLayout".
    LinearLayout layout = (LinearLayout)findViewById(R.id.mainLayout);

    // Add the adView to it.
    layout.addView(adView);

    // Initiate a generic request.
    AdRequest adRequest = new AdRequest.Builder().build();

    // Load the adView with the ad request.
    adView.loadAd(adRequest);
  }    
}

这是我不应该使用的 xml 布局的代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

</LinearLayout>

这是我想成为主要内容视图的 java 文件的代码：

import android.content.Context;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.view.MotionEvent;
import android.view.View;

public class TitleView extends View {

private Bitmap titleGraphic;
private Bitmap playButtonUp;
private Bitmap playButtonDown;
private int screenW;
private int screenH;
private boolean playButtonPressed;
private Context myContext;

public TitleView(Context context) {
    super(context);
    myContext = context;
    titleGraphic = BitmapFactory.decodeResource(getResources(), R.drawable.title_graphic);
    playButtonUp = BitmapFactory.decodeResource(getResources(), R.drawable.play_button_up);
    playButtonDown = BitmapFactory.decodeResource(getResources(), R.drawable.play_button_down);
}

@Override
public void onSizeChanged (int w, int h, int oldw, int oldh){
    super.onSizeChanged(w, h, oldw, oldh);
    screenW = w;
    screenH = h;
    System.out.println("SCREEN W: " + screenW);
    System.out.println("SCREEN H: " + screenH);
}

@Override 
protected void onDraw(Canvas canvas) {
    canvas.drawBitmap(titleGraphic, (screenW-titleGraphic.getWidth())/2, 0, null);
    if (playButtonPressed) {
        canvas.drawBitmap(playButtonDown, (screenW-playButtonUp.getWidth())/2, (int)(screenH*0.7), null);   
    } else {
        canvas.drawBitmap(playButtonUp, (screenW-playButtonUp.getWidth())/2, (int)(screenH*0.7), null);         
    }
}



 public boolean onTouchEvent(MotionEvent event) {
        int eventaction = event.getAction();   
        int X = (int)event.getX();
        int Y = (int)event.getY();

        switch (eventaction ) {

        case MotionEvent.ACTION_DOWN: 
            if (X > (screenW-playButtonUp.getWidth())/2 &&
                X < ((screenW-playButtonUp.getWidth())/2) + playButtonUp.getWidth() &&
                Y > (int)(screenH*0.7) &&
                Y < (int)(screenH*0.7) + playButtonUp.getHeight()) {
                playButtonPressed = true;
            }                   
            break;

        case MotionEvent.ACTION_MOVE: 
            break;

        case MotionEvent.ACTION_UP:
            if (playButtonPressed) {
                Intent gameIntent = new Intent(myContext, GameActivity.class);
                myContext.startActivity(gameIntent);                    
            }
            playButtonPressed = false;
            break;
        } 
        invalidate();
        return true;      
}
}

首先将Google Mobile Ads SDK放入lib文件夹

在Admob 上激活您的帐户后，您需要在您的帐户中配置一个应用程序。在该应用程序之后，Admob 将为您提供 Admob 的 Android SDK，其中包含 admob.jar 和工作示例。

private void AdmobFooterInitialize(){
    adView = new AdView(this, AdSize.SMART_BANNER, "Your_AdMobPUBLISHERID");
    LinearLayout layout = (LinearLayout)findViewById(R.id.linear);
    layout.addView(adView);
    AdRequest request = new AdRequest();
    request.addTestDevice("your device id"); // this for testing 
    request.setTesting(false);
    adView.loadAd(request);
}

在你的 manifest.xml 中

 <meta-data android:value="true" android:name="ADMOB_ALLOW_LOCATION_FOR_ADS" />
 <activity android:name="com.google.ads.AdActivity"
  android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>

如何获取deviceId：-

final TelephonyManager tm =(TelephonyManager)getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);

String deviceid = tm.getDeviceId();

我认为这个例子对你有帮助

Answer 2

我发现使用adMob 在文件中明确定义布局可能是一个非常令人头疼的生成器，因为有时它可能会因某些参数和布局组合而变得难以预测。似乎总是有效的是将AdView动态添加到一些LinearLayout。

这应该可行：

final LinearLayout yourLayout = (LinearLayout) findViewById(R.id.your_linearlayout_id_where_you_want_to_put_your_adview);

final AdView adView = new AdView(this);
adView.setAdUnitId("your-admob-id");
adView.setAdSize(AdSize.BANNER);

yourLayout.addView(adView);

final AdRequest.Builder adReq = new AdRequest.Builder();
// You should include a line like this for testing purposes,
// but only after you've tested whether your AdView works!
// This will prevent your ad being loaded each time you test
// your ad, so it will prevent you being blocked from AdMob.
// You'll find your device_id in the LogCat.
adReq.addTestDevice("your_device_id");

final AdRequest adRequest = adReq.build();
adView.loadAd(adRequest);

Answer 3

我会通过 XML 配置您的 TitleView。例如，将您的布局更改为：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<your.titleview.package.name.here.TitleView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

</LinearLayout>

并删除在 onCreate 中构造它的代码。
