这里是第15行，它在“onCreate” - >上显示错误-i.e

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main); //line no 15 in my code(indicated in the logcat)
}

在你的清单中使用它：

<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">

添加清单文件android：hardwareAccelerated =“false”，android：largeHeap =“true”它适用于某些环境。

<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">

使用像Glide和Picasso这样的图像加载库。对于Glide：

public static void loadToGlide(Context context, ImageView imageView, Object o) {
        Glide.with(context)
                .asBitmap()
                .apply(new RequestOptions()
                        .centerCrop())
                .transition(new BitmapTransitionOptions()
                        .crossFade())
                .load(o)
                .into(imageView);
    }

致电：

loadToGlide(context, yourImageView, R.drawable.yourImage);

他们将为您处理一切，尤其是OutOfMemoryError。

您可以使用recylerview而不是多个imagviews，并且可以使用volley imageloader或glide来加载seamlessely。
