針對1.5開發的應用程序未在2.2 android

Question

上運行我已經從聯機教程中查看大圖片的代碼。 它工作正常1.5，但是當我使用Android 2.2庫它不起作用。 （我的應用程序使用2.2） 我已經搜索了這個問題的答案，但沒有運氣。我懷疑它可以與可繪製的文件夾有關嗎？ 圖像加載，但無法完成縮放或移動圖像等操作。

private void updateDisplay(){ 
    calculateSourceRect(current_centerX, current_centerY, current_scale); 
    //where sourceRect = new RectF(); and destinationRect = new RectF(); 
    matrix.setRectToRect(sourceRect, destinationRect, Matrix.ScaleToFit.FILL); 
    androidBigImageView.setImageMatrix(matrix); 
} 

private void calculateSourceRect(int centerX, int centerY, float scale){ 
    int xSubValue; 
    int ySubValue; 

    if(destinationRect.bottom >= destinationRect.right){ 
     ySubValue = (int)((imageSizeY/2)/scale); 
     xSubValue = ySubValue; 

     xSubValue = (int) (xSubValue * ((float)androidBigImageView.getWidth()/(float)androidBigImageView.getHeight())); 
    } 
    else{ 
     xSubValue = (int)((imageSizeX/2)/scale); 
     ySubValue = xSubValue; 

     ySubValue = (int) (ySubValue * ((float)androidBigImageView.getHeight()/(float)androidBigImageView.getWidth())); 
    } 

    if(centerX - xSubValue < 0) { 
     animation.stopProcess(); 
     centerX = xSubValue; 
    } 
    if(centerY - ySubValue < 0) { 
     animation.stopProcess(); 
     centerY = ySubValue; 
    } 
    if(centerX + xSubValue >= imageSizeX) { 
     animation.stopProcess(); 
     centerX = imageSizeX - xSubValue - 1; 
    } 
    if(centerY + ySubValue >= imageSizeY) { 
     animation.stopProcess(); 
     centerY = imageSizeY - ySubValue - 1; 
    } 

    current_centerX = centerX; 
    current_centerY = centerY; 

    sourceRect.set(centerX - xSubValue, centerY - ySubValue, centerX + xSubValue, centerY + ySubValue); 
}

嘗試androidBigImageView.setScaleType(ScaleType.MATRIX);
