将整数值存储到文件中

问题描述：

for (Point point : landmarks) 
{ 
    for (int i = 48; i <= 66; i++) 
    { 
     point = landmarks.get(i); 
     //Log.d(TAG,"landmarks (" + landmarks.get(i) +")"); 
     int pointX = (int) (point.x * resizeRatio); 
     int pointY = (int) (point.y * resizeRatio); 

     Log.d(TAG,"My points:(" + pointX +","+ pointY +")"); 

     point=landmarks.get(i+1); 

     int pointXX = (int) (point.x * resizeRatio); 
     int pointYY = (int) (point.y * resizeRatio); 

     canvas.drawLine(pointX, pointY, pointXX, pointYY, mFaceLandmardkPaint); 
    } 
}

从上面的代码我必须访问整数值到变量，pointX和pointY.How可以在必须将这些值存储到一个文件？将整数值存储到文件中

您搜索到_how在第一档中的数据写入？网上有足够的教程。 – AxelH

String lipfile =“lip-data”; FileOutputStream fout = new FileOutputStream（“/ sdcard /”+ lipfile +“。txt”）;尝试{fout.write（65）; //fout.write（pointX）; catch（IOException e）{ e.printStackTrace（）; }。使用此代码数据将文件写入为“A”。该符号代表ASCII值65. – Ammu

因此，您可以在一个文件中写入，这是什么问题？ – AxelH

答

尝试

try{ 
    PrintWriter writer = new PrintWriter("the-file-name.txt", "UTF-8"); 

    for (int i = 48; i <= 66; i++) 
    { 
     point = landmarks.get(i); 
     //Log.d(TAG,"landmarks (" + landmarks.get(i) +")"); 
     int pointX = (int) (point.x * resizeRatio); 
     int pointY = (int) (point.y * resizeRatio); 

     Log.d(TAG,"My points:(" + pointX +","+ pointY +")"); 

     point=landmarks.get(i+1); 

     int pointXX = (int) (point.x * resizeRatio); 
     int pointYY = (int) (point.y * resizeRatio); 

     canvas.drawLine(pointX, pointY, pointXX, pointYY, mFaceLandmardkPaint); 

     writer.println(pointX + ",+ pointY + ","+pointXX+","+pointYY); 
    } 


    writer.close(); 
} catch (IOException e) { 
    // do something 
}

我试过这个，但没有得到任何答案。 – Ammu
