我正在尝试实现谷歌的选项卡 SlidingTabLayout。选项卡将显示在屏幕的下半部分，而上半部分包含普通的文本和 ImageView 。我知道 View 实现中有问题，但我无法准确地弄清楚。
对于 java.lang.OutOfMemoryError，我尝试将 RAM 值设置为等于 HAXM 值，并将 VM 堆增加到 256MB，但它仍然给出相同的错误。
错误:

最佳答案
问题是您在 RelativeLayout 中设置的背景
android:background="@drawable/profile_page_background_blur"
位图尺寸太大，主线程无法处理，您应该缩小位图并设置背景。
AsyncTask可以用来做到这一点:
public class ImageLoadTask extends AsyncTask<Integer, Void, Bitmap> {
private TaskCallback callback;
private Activity activity;
public ImageLoadTask(Activity activity) {
this.callback = activity;
this.activity = activity;
}
@Override
protected Bitmap doInBackground(Integer... params) {
Bitmap bitmap;
Display display = activity.getWindowManager().getDefaultDisplay();
Point size = new Point();
int width;
int height;
if (Build.VERSION.SDK_INT > 13) {
display.getSize(size);
width = size.x;
height = size.y;
} else {
width = display.getWidth();
height = display.getHeight();
}
return scaledDownBitmap(params[0], width, height);
}
@Override
protected void onPostExecute(Bitmap bitmap) {
super.onPostExecute(bitmap);
callback.onImageLoaded(bitmap);
}
public interface TaskCallback {
void onImageLoaded(Bitmap bitmap);
}
public Bitmap scaledDownBitmap(int resource, int reqWidth, int reqHeight) {
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeResource(activity.getResource(), resource, options);
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
options.inJustDecodeBounds = false;
Bitmap bitmap = BitmapFactory.decodeFile(path, options);
Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight());
return resizedBitmap;
}
public static int calculateInSampleSize(BitmapFactory.Options options,
int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and
// keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
}
让您的 Activity 实现 ImageLoadTask.TaskCallback 并在那里设置 RelativeLayout 的背景。
要使用AsyncTask，请执行以下操作:
ImageLoadTask task = new ImageLoadTask(this);
task.execute(R.drawable.profile_page_background_blur)
并在任务的回调中执行以下操作:
@Override
public void onImageLoaded(Bitmap bitmap) {
view.setBackground(new BitmapDrawable(getResouce(), bitmap));
}
我希望这有帮助。
始终记住将位图工作卸载到单独的线程中，查看 this和 this 。您还应该考虑使用 Picasso或Glide或任何其他第三方库。它们简化了您的工作:)
