我尝试通过使用相机来捕获图像并将其设置为我的应用中的个人资料图片。
相机会捕捉图像，但在配置文件中没有设置任何图片，仍为空白，并希望将该图片上传到我的服务器。
在通过DataInputStream读取图片时，它说，“不推荐使用DataInputStream类型的方法readLine（）”。
帮我解决这个问题。
这是我的代码：
public void settings(){
AlertDialog.Builder alertDialog2 = new AlertDialog.Builder(SignUp.this);
alertDialog2.setTitle("");
alertDialog2.setMessage("Please select an image..");
alertDialog2.setIcon(R.drawable.act_camera);
alertDialog2.setPositiveButton("CAMERA.",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
condition="from_camera";
pd = ProgressDialog.show(SignUp.this, "", "Please wait...", true);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAM_REQUREST);
}
});
alertDialog2.setNegativeButton("GALLERY.",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
condition="from_gallery";
pd = ProgressDialog.show(SignUp.this, "", "Please wait...", true);
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
alertDialog2.show();
}

将该图像文件发送到服务器
HttpClient httpclient;
httpclient = HttpClientSingalTon.getHttpClienttest();
HttpPost httpPostRequest = new HttpPost(URL);
// Try This
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(yourimagefile, "image/jpeg");
mpEntity.addPart("file", cbFile);
httpPostRequest.setEntity(mpEntity);
HttpResponse response = (HttpResponse) httpclient.execute(httpPostRequest);

如果您能够获取图像的路径，那么尝试从该路径获取图像。 有一种替代方法可以在服务器上上传图像。您可以使用Base64编码将图像转换为Sting，并通过JSON将该字符串发送到您的服务器。
