Question

通过扩展视图创建自定义视图并将其排列在布局中。现在尝试将位图设置为自定义视图背景但未获得如何操作请求帮助。在这里我正在添加我的主要课程

public class CreatePeeqsActivity extends Activity implements OnClickListener {

private ImageView ivImage, ivCountTimer;
private TextView tvUndo, tvNext;
private ImageView ivFont, ivSquare, ivRectangle, ivLine, ivCircle, ivOval;
PhotoSortrView photoSorter;
final Context context = this;
//EditText editTextAddText;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    photoSorter = new PhotoSortrView(this);
    setContentView(R.layout.activity_create_peeqs);

    getIds();
    byte[] byteArray = getIntent().getByteArrayExtra("BitmapImage");
    Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0,
            byteArray.length);


}

只需将位图转换为drawable并将其设置为视图的背景。

byte[] byteArray = getIntent().getByteArrayExtra("BitmapImage");
        Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0,
                byteArray.length);

        Drawable d = new BitmapDrawable(getResources(),bmp);

        photoSorter.setBackground(d);

        //or

        photoSorter.setBackgroundDrawable(d);
