我正在使用合并两个image的代码，并在canvas中将它们显示在一起，如下所示。你能说store作为single image。
public class ChoosePictureComposite extends Activity implements OnClickListener {
static final int PICKED_ONE = 0;
static final int PICKED_TWO = 1;
boolean onePicked = false;
boolean twoPicked = false;
Button choosePicture1, choosePicture2;
ImageView compositeImageView;
Bitmap bmp1, bmp2;
Canvas canvas;
Paint paint;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
compositeImageView = (ImageView) this
.findViewById(R.id.CompositeImageView);
choosePicture1 = (Button) this.findViewById(R.id.ChoosePictureButton1);
choosePicture2 = (Button) this.findViewById(R.id.ChoosePictureButton2);
choosePicture1.setOnClickListener(this);
choosePicture2.setOnClickListener(this);
}
public void onClick(View v) {
int which = -1;
if (v == choosePicture1) {
which = PICKED_ONE;
} else if (v == choosePicture2) {
which = PICKED_TWO;
}
Intent choosePictureIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(choosePictureIntent, which);
}
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_OK) {
Uri imageFileUri = intent.getData();
if (requestCode == PICKED_ONE) {
bmp1 = loadBitmap(imageFileUri);
onePicked = true;
} else if (requestCode == PICKED_TWO) {
bmp2 = loadBitmap(imageFileUri);
twoPicked = true;
}
if (onePicked && twoPicked) {
Bitmap drawingBitmap = Bitmap.createBitmap(bmp1.getWidth(),
bmp1.getHeight(), bmp1.getConfig());
canvas = new Canvas(drawingBitmap);
paint = new Paint();
canvas.drawBitmap(bmp1, 90, 0, paint);
// paint.setXfermode(new PorterDuffXfermode(
// android.graphics.PorterDuff.Mode.MULTIPLY));
canvas.drawBitmap(bmp2, 30, 40, paint);
compositeImageView.setImageBitmap(drawingBitmap);
}
}
}
private Bitmap loadBitmap(Uri imageFileUri) {
Display currentDisplay = getWindowManager().getDefaultDisplay();
float dw = currentDisplay.getWidth();
float dh = currentDisplay.getHeight();
Bitmap returnBmp = Bitmap.createBitmap((int) dw, (int) dh,
Bitmap.Config.ARGB_4444);
try {
// Load up the image's dimensions not the image itself
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = true;
returnBmp = BitmapFactory.decodeStream(getContentResolver()
.openInputStream(imageFileUri), null, bmpFactoryOptions);
int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight / dh);
int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth / dw);
Log.v("HEIGHTRATIO", "" + heightRatio);
Log.v("WIDTHRATIO", "" + widthRatio);
// If both of the ratios are greater than 1, one of the sides of the
// image is greater than the screen
if (heightRatio > 1 && widthRatio > 1) {
if (heightRatio > widthRatio) {
// Height ratio is larger, scale according to it
bmpFactoryOptions.inSampleSize = heightRatio;
} else {
// Width ratio is larger, scale according to it
bmpFactoryOptions.inSampleSize = widthRatio;
}
}
// Decode it for real
bmpFactoryOptions.inJustDecodeBounds = false;
returnBmp = BitmapFactory.decodeStream(getContentResolver()
.openInputStream(imageFileUri), null, bmpFactoryOptions);
} catch (FileNotFoundException e) {
Log.v("ERROR", e.toString());
}
return returnBmp;
}
}

试试这个：
public class Aura extends Activity {
protected static final String TAG = Aura.class.getName();
private static String mTempDir;
Bitmap mBackImage, mTopImage, mBackground, mInnerImage, mNewSaving;
Canvas mComboImage;
FileOutputStream mFileOutputStream;
BitmapDrawable mBitmapDrawable;
private String mCurrent = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.aura);
mTempDir = Environment.getExternalStorageDirectory() + "/" + "Aura" + "/";
mCurrent = "Aura.png";
prepareDirectory();
mBackground = Bitmap.createBitmap(604, 1024, Bitmap.Config.ARGB_8888);
mBackImage = BitmapFactory.decodeResource(getResources(), R.drawable.aura);
mTopImage = BitmapFactory.decodeResource(getResources(), R.drawable.test);
mInnerImage = BitmapFactory.decodeResource(getResources(), R.drawable.anothertest);
mComboImage = new Canvas(mBackground);
mComboImage.drawBitmap(mBackImage, 0f, 0f, null);
mComboImage.drawBitmap(mTopImage, 0f, 0f, null);
mComboImage.drawBitmap(mInnerImage, 0f, 0f, null);
mFileOutputStream = null;
mSave.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.v(TAG, "Save Tab Clicked");
try {
mBitmapDrawable = new BitmapDrawable(mBackground);
mNewSaving = ((BitmapDrawable) mBitmapDrawable).getBitmap();
String FtoSave = mTempDir + mCurrent;
File mFile = new File(FtoSave);
mFileOutputStream = new FileOutputStream(mFile);
mNewSaving.compress(CompressFormat.PNG, 95, mFileOutputStream);
mFileOutputStream.flush();
mFileOutputStream.close();
} catch (FileNotFoundException e) {
Log.v(TAG, "FileNotFoundExceptionError " + e.toString());
} catch (IOException e) {
Log.v(TAG, "IOExceptionError " + e.toString());
}
}
});
}//onCreate
private boolean prepareDirectory() {
try {
if (makeDirectory()) {
return true;
} else {
return false;
}
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(this, getString(R.string.sdcard_error), 1000).show();
return false;
}
}
private boolean makeDirectory() {
File mTempFile = new File(mTempDir);
if (!mTempFile.exists()) {
mTempFile.mkdirs();
}
if (mTempFile.isDirectory()) {
File[] mFiles = mTempFile.listFiles();
for (File mEveryFile : mFiles) {
if (!mEveryFile.delete()) {
System.out.println(getString(R.string.failed_to_delete) + mEveryFile);
}
}
}
return (mTempFile.isDirectory());
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((!(android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.DONUT)
&& keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0)) {
onBackPressed();
}
return super.onKeyDown(keyCode, event);
}
public void onBackPressed() {
finish();
}
}

创建一个新的Bitmap，其中包含图像各个高度的高度和。
Bitmap newBitmap = Bitmap.createBitmap(widht
, totalHeight, Config.ARGB_8888);
Canvas canvas = new Canvas(newBitmap);
canvas.drawBitmap(image11, 0, 0, null);
canvas.drawBitmap(image2, 0, image1Height, null);
这应该将2个图像绘制到newBitmap，一个在另一个之下。如果您想要并排高度参数，请将其更改为
这是你在找什么？
