我从教程网站复制了这段代码,因为我正在努力学习它.但是我收到了错误

package com.android.test;
import android.R;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Matrix;
import android.graphics.drawable.BitmapDrawable;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.SeekBar;
import android.widget.Spinner;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import android.widget.ImageView.ScaleType;
public class Rotate extends Activity {
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         LinearLayout linearLayout = new LinearLayout(this);

   Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.icon);

在最后一行,我得到一个错误,其中写有".icon".它说,"图标无法解析或不是一个领域."

int width = bitmap.getWidth(); int height = bitmap.getHeight();

   Matrix matrix = new Matrix();
   matrix.postRotate(90);

   Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap, 0, 0,

Run Code Online (Sandbox Code Playgroud)

width,height,matrix,true); …
