Question

我在android上阅读了很多关于位图的帖子，找不到任何符合我代码的解释。我正在从SD卡中的摄像头保存图像，而不是当我尝试显示所有图像时，我得到了错误。

我的代码：

showAttachment(atts);

其中atts是一个Array os路径

private void showAttachment(List<Attachment> atts) {

    for(Attachment att : atts){
        insertPhoto(getBitmap(att.getPath()));
    }

}

public Bitmap getBitmap(String path){

    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = false;
    bmOptions.inPurgeable = true;

    Bitmap bitmap = BitmapFactory.decodeFile(path, bmOptions);

    return bitmap;

}

public void insertPhoto(Bitmap btmp){
    final ViewGroup newView = (ViewGroup) LayoutInflater.from(this).inflate(
            R.layout.photo_item, mContainerView, false);


    newView.setBackground(new BitmapDrawable(getResources(),btmp));
    ImageView delete = (ImageView) newView.findViewById(R.id.photo_expense_discart);
    delete.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            //mContainerView.removeView(newView);
            Intent imageDetil = new Intent(InsertItem.this,ImageDetailActivity.class);
            InsertItem.this.startActivity(imageDetil);
        }
    });

    mContainerView.addView(newView, 0);
}

我的XML：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="130dp"
android:layout_height="130dp"
android:layout_margin="5dp"
android:orientation="vertical" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="30dp"
    android:alpha="80"
    android:background="#80000000"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/photo_expense_discart"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/ic_content_discard_w" />
</LinearLayout>

如果我这样做，一张图片工作正常，但当我尝试显示多个时，我得到错误，有人知道我该如何解决？谢谢

检查您提供的这段代码：

public Bitmap getBitmap(String path){

    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = false;
    bmOptions.inPurgeable = true;

    Bitmap bitmap = BitmapFactory.decodeFile(path, bmOptions);

    return bitmap;

}

在行Bitmap bitmap = BitmapFactory.decodeFile(path, bmOptions);中，您可能尝试将文件解码得太大，从而导致内存异常。
