イムアップロードファイルやプログレスバーを使用しようとイムを凍結します：progressdialogバー私はこのコードでアップロードを開始
@Override
public void onClick(View v) {
if(v== ivAttachment){
//on attachment icon click
showFileChooser();
}
if(v== bUpload){
//on upload button Click
if(selectedFilePath != null){
dialog = new ProgressDialog(upload.this);
dialog.setMax(100);
dialog.setMessage("Subiendo Archivo...");
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
dialog.setProgress(0);
dialog.show();
//dialog.show(upload.this,"","Subiendo Archivo...",true);
new Thread(new Runnable() {
@Override
public void run() {
//creating new thread to handle Http Operations
uploadFile(selectedFilePath);
}
}).start();
}else{
Toast.makeText(upload.this,"Escoge un archivo",Toast.LENGTH_SHORT).show();
}
}
}
その後、uploadFile（selectedFilePath）。ここから私のコードの一部です：
private class ProgressUpdater implements Runnable {
private long mUploaded;
private long mTotal;
public ProgressUpdater(long uploaded, long total) {
mUploaded = uploaded;
mTotal = total;
}
@Override
public void run() {
onProgressUpdate((int)(100 * mUploaded/mTotal));
}
}
public void onProgressUpdate(int percentage) {
// set current progress
dialog.setProgress(percentage);
}
これまでのところ、私はその作業を考えていますが、アップロードまで、100分の14のように、いくつかの数にフリーズ：私はこれを持っているクラスのうち、その後、
File sourceFile = new File(selectedFilePath);
int totalSize = (int)sourceFile.length();
HttpURLConnection connection;
DataOutputStream dataOutputStream;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead,bytesAvailable,bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File selectedFile = new File(selectedFilePath);
String[] parts = selectedFilePath.split("/");
final String fileName = parts[parts.length-1];
if (!selectedFile.isFile()){
dialog.dismiss();
runOnUiThread(new Runnable() {
@Override
public void run() {
tvFileName.setText("Source File Doesn't Exist: " + selectedFilePath);
}
});
return 0;
}else{
try{
FileInputStream fileInputStream = new FileInputStream(selectedFile);
URL url = new URL(SERVER_URL);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);//Allow Inputs
connection.setDoOutput(true);//Allow Outputs
connection.setUseCaches(false);//Don't use a cached Copy
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("ENCTYPE", "multipart/form-data");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
connection.setRequestProperty("uploaded_file",selectedFilePath);
//creating new dataoutputstream
dataOutputStream = new DataOutputStream(connection.getOutputStream());
//writing bytes to data outputstream
dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
+ selectedFilePath + "\"" + lineEnd);
dataOutputStream.writeBytes(lineEnd);
//returns no. of bytes present in fileInputStream
bytesAvailable = fileInputStream.available();
//selecting the buffer size as minimum of available bytes or 1 MB
bufferSize = Math.min(bytesAvailable,maxBufferSize);
//setting the buffer as byte array of size of bufferSize
buffer = new byte[bufferSize];
//reads bytes from FileInputStream(from 0th index of buffer to buffersize)
bytesRead = fileInputStream.read(buffer,0,bufferSize);
int totalBytesWritten = 0;
Handler handler = new Handler(Looper.getMainLooper());
//loop repeats till bytesRead = -1, i.e., no bytes are left to read
while (bytesRead > 0) {
//write the bytes read from inputstream
dataOutputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
totalBytesWritten += bytesRead;
handler.post(new ProgressUpdater(totalBytesWritten, totalSize));
}
dataOutputStream.writeBytes(lineEnd);
dataOutputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
