标签: progressdialog

我想在android中使用自定义微调器图像来进行dialod我为此目的使用.gif文件,并通过此代码应用它,

dialog = new ProgressDialog(BackupRestoreActivityContext);    
dialog.setCancelable(true);    
dialog.setIcon(resId);    
dialog.setTitle(title);    
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);    
dialog.setIndeterminate(true);
dialog.setIndeterminateDrawable(BackupRestoreActivityContext.getResources().getDrawable(R.drawable.bar));    
dialog.show();

通过此代码Spinner图像更改为bar.gif但它没有旋转,请帮助我这是错误的,谢谢任何帮助在这方面非常感谢.

我有一个异步任务,它不会在完成任务时添加百分比.它始终保持在0%0/100

这是我的代码

     private class getAppInfo extends AsyncTask<String, String, String> {
    /** The system calls this to perform work in a worker thread and
      * delivers it the parameters given to AsyncTask.execute() */
    ProgressDialog dialog;

    @Override
    protected void onPreExecute() {
        if(showLoading == true){
             dialog = new ProgressDialog(SelfHelp.this);
             dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
             dialog.setMessage("Loading");
             dialog.setIndeterminate(true);
             dialog.setCancelable(false);   
             dialog.setMax(100);
             dialog.setProgress(100);
             dialog.show();
        }
    }

    @Override
    protected String doInBackground(String... urls) {                       
        String xml = null;
        int count = 0;
        try {
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpGet httpGet …

我正在尝试将ProgressDialog移动到我的ActionBar.

我知道如何将它放在动作栏中并为其设置动画(我认为),如下所示:

在progress.xml中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:weightSum="1" >

    <ProgressBar
        android:id="@+id/progress"
        style="?android:attr/progressBarStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >
    </ProgressBar>

</LinearLayout>

在menu.xml中

<item
    android:id="@+id/Refresh"
    android:icon="@drawable/ic_menu_refresh"
    android:showAsAction="always"
    android:title="Refresh"/>

在我的活动中

    case R.id.Refresh:
        item.setActionView(R.layout.progress);
        return true;

这里是我目前的PD(在活动)onPreExecute和onPostExecute我的AsyncTask的:

// Pre  
dialog = new MyProgressDialog(---.this);
dialog.show(---.this);


// Post    
dialog.dismiss(---.this);

那么如何移动它以便激活操作栏指示器onPreExecute然后停止onPostExecute？

编辑:当你第一次加载一个活动(或做一些需要PD激活的东西)时,我不仅要寻找刷新,而且还要寻找"加载"指示器.它应该默认隐藏.

我已经为进度对话框制作了自定义样式,但它周围有奇怪的边框.

这是主题:

<style name="AppTheme.Dialog" parent="Theme.AppCompat.Light.Dialog">
    <item name="colorAccent">@android:color/white</item>
    <item name="android:textColorPrimary">@android:color/white</item>
    <item name="android:background">@color/colorPrimaryDark</item>
    <item name="android:popupBackground">@null</item>
</style>

任何想法为什么会有如此奇怪的背景？

我正在上传字符串和照片.它的工作正常.现在我想显示进度条,同时上传数据百分比,但百分比显示很快达到100%,并花费更多时间上传,最后进入后执行方法.

protected class upload_images extends AsyncTask<String, Integer, String> {
        ProgressDialog progressDialog;
            @Override
            protected void onPreExecute() {
                super.onPreExecute();
               // showDialog(progress_bar_type);
                progressDialog = new ProgressDialog(Accept_Report.this);
                progressDialog.setCancelable(false);
                //  dialog.setCanceledOnTouchOutside(false);
                progressDialog.setIndeterminate(false);
              //  progressDialog.setMax(100);
                progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
               // progressDialog.setProgress(0);
                progressDialog.setMax(100);
               // progressDialog.setMessage("Loading ...");
                progressDialog.show();
             //  ProgressBar progressBar = (ProgressBar)findViewById(R.id.progressBar2);
            }
            @Override
            protected String doInBackground(String... params) {
                URL url;
                HttpURLConnection connection = null;
                String http=Util.URL+"reports/media/create";
                try {
                    url = new URL(http);
                    connection = (HttpURLConnection) url.openConnection();
                    connection.setDoInput(true);

                    connection.setReadTimeout(50000);*/
                    connection.setRequestProperty("Content-Type", "application/json");
                    connection.setRequestProperty("Content-Language", "en-US");

我不知道如何定位进度对话框(带有旋转图像的对话框).当我的应用程序开始显示全屏图像和进度对话框时.我需要将进度对话框稍微降低一点.

谢谢Rajesh

我已经在stackoverflow上查看了Android API和其他帖子,但一直无法解决这个问题.

我的应用程序将文件下载到SD卡.我想在文件下载时弹出"加载..."对话框,然后在下载完成后消失.这是我使用android API提出的:

ProgressDialog pd = ProgressDialog.show(this,"","Loading. Please wait...",true);

//download file

pd.cancel();

但是对话框实际上并没有显示.当我调试它时,它声称它正在显示,但它显然不在屏幕上.

我能做什么？

我已经坚持了一段时间.我有一个异步任务,将图像上传到Web服务器.工作良好.

我为此设置了一个进度条对话框.我的问题是如何准确更新进度条.我尝试的所有东西都会导致它从一步到0-100.如果需要5秒或2分钟则无关紧要.上传完成后,栏会挂到0然后点击100.

这是我的doInBackground代码.任何帮助表示赞赏.

编辑:我更新了下面的代码,包括整个AsynchTask

private class UploadImageTask extends AsyncTask<String,Integer,String> {

        private Context context;   
        private String msg = "";
        private boolean running = true;

        public UploadImageTask(Activity activity) {
            this.context = activity;
            dialog = new ProgressDialog(context);
            dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            dialog.setMessage("Uploading photo, please wait.");
            dialog.setMax(100);
            dialog.setCancelable(true);
        }


    @Override
    protected void onPreExecute() {
            dialog.show();
            dialog.setOnDismissListener(mOnDismissListener);
    }



    @Override
    protected void onPostExecute(String msg){

         try {
        // prevents crash in rare case where activity finishes before dialog
        if (dialog.isShowing()) {
                dialog.dismiss();
        }
              } catch (Exception e) {
              } 
     } …

我有一个带有按钮的Android活动/布局.当我单击此按钮时,它会打开一个带有2个微调器的DialogFragment.当DialogFragment出现时,我需要使用Web服务返回的项填充这两个微调器.因此,在等待服务返回时,我想在我刚刚打开的DialogFragment上显示ProgressDialog.

问题是我似乎无法将ProgressDialog置于DialogFragment之上.我可以看到ProgressDialog显示在DialogFragment后面,是否可以将ProgressDialog显示在其他所有内容上？

我的代码是这样的:

public class RegionalFragment extends DialogFragment {

    private View view;
    private Activity activity;
    private Spinner spinner1;
    private Spinner spinner2;
    private ProgressDialog progressDialog;

    public RegionalFragment(Activity activity) {
        this.activity = activity;
        LayoutInflater inflater = activity.getLayoutInflater();
        view = inflater.inflate(R.layout.spinner_selection, null);
        this.progressDialog = new ProgressDialog(activity);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder =
            new AlertDialog.Builder(activity)
                    .setTitle(R.string.title)
                    .setView(view)
                    .setPositiveButton(R.string.ok, new MyListener(activity))
                    .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            getDialog().cancel();
                        }
                    });

        progressDialog.getWindow().setBackgroundDrawable(new ColorDrawable(1));
        progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        progressDialog.setCancelable(false);
        progressDialog.setIndeterminate(true);
        progressDialog.setMessage("Please …
