我正在实施谷歌提供的原生广告代码.这样做还可以google

广告单元ID ADMOB_AD_UNIT_ID ="ca-app-pub-3940256099942544/2247696110"

但当我用我的id替换它没有显示广告和执行onAdFailedToLoad方法并且 无法加载原生广告:0错误.

I tried two different ad unit id but it didn't load ad.

so what should I do??please help me 

我试过下面的代码

final LayoutInflater li = (LayoutInflater) appContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            AdLoader.Builder builder = new AdLoader.Builder(appContext, Global.ADMOB_AD_UNIT_ID);

            builder.forContentAd(new NativeContentAd.OnContentAdLoadedListener() {
                @Override
                public void onContentAdLoaded(NativeContentAd ad) {
                    //viewHolder.rlnativead.setVisibility(View.VISIBLE);
                    NativeContentAdView adView = (NativeContentAdView)li
                            .inflate(R.layout.ad_content, null);
                    populateContentAdView(ad, adView);
                    viewHolder.fl_adplaceholder.removeAllViews();
                    viewHolder.fl_adplaceholder.addView(adView);
                }
            });

            AdLoader adLoader = builder.withAdListener(new AdListener() {
                @Override
                public void onAdFailedToLoad(int errorCode) {
//                  Toast.makeText(appContext, "Failed to …

我想在旋转车轮时播放声音根据角度和坐标轮的旋转速度

当Pin触​​摸在线触摸Arc时,我想在正确的时间播放Sound Play.

此外,想要动画在Pin上像触摸一样震动.

声音是播放但是声音连续播放并且根据画布轮不寻求坐标

    super.onDraw(canvas);
    drawWheelBackground(canvas);
    initComponents();

    float tempAngle = 0;
    float sweepAngle = 360 / mWheelItems.size();
    if (this.mWheelItems != null) {

        Log.e("mWheelItems.size()", String.valueOf(mWheelItems.size()));
        for (int i = 0; i < mWheelItems.size(); i++) {
            archPaint.setColor(mWheelItems.get(i).color);
            archPaint1.setColor(Color.WHITE);

            canvas.drawArc(range, tempAngle, sweepAngle, true, archPaint2);
            canvas.drawArc(range, tempAngle, sweepAngle, true, archPaint);

            drawImage(canvas, tempAngle, mWheelItems.get(i).bitmap, mWheelItems.get(i).mvalue, sweepAngle);

        }

       if (!(this.resourcePlayer == null)) {

我正在尝试将一个片段插入另一个片段，并且我已经成功做到这一点，直到我第一次吃完主要片段为止，但是当我尝试重新加载片段时，应用崩溃了，我有这个错误：

这是我的片段

Bundle savedInstanceState) {

我想生成这样的随机数

• ADF1845CFT

• ADF1864ATY

• ADF18AT65Y

注意:在那里我修复了ADF18我想只需要接下来的5位数字和包机

我成功创建了带数字的5位数字

我正在使用各种解决方案

• 如何组合随机数矩阵

• 具有给定长度的Java随机数

等方法

通过这些方法,我创建了成功的随机5位数字.

任何帮助欣赏......
