我沒有太大的成功這樣做,我認爲會工作,所以我會問專家。在對話框中顯示圖片的變化循環?
我有一個鏈接到圖像的10個URL的ArrayList。我想要顯示第一個網址2秒,然後獲取第二個網址並執行相同的操作直到結束。
這是我到目前爲止,我想也許我不是在postExecute對話?:
private class LiveView extends AsyncTask<String, Integer, ArrayList<String>> {
ProgressDialog dialog;
private volatile boolean running = true;
@Override
protected void onPreExecute() {
dialog = ProgressDialog.show(
myView.this,
"Working",
"Info message . . .",
true,
true,
new DialogInterface.OnCancelListener(){
public void onCancel(DialogInterface dialog) {
cancel(true);
}
}
);
}
@Override
protected void onCancelled() {
running = false;
}
@Override
protected ArrayList<String> doInBackground(String... passed) {
while (running) {
//removed the code here that sends the request to to make this shorter the server but it works fine
return responseFromServer.arrayListofURLs; //list or URLs
}
return null;
}
@Override
protected void onPostExecute(ArrayList<String> listURLs) {
dialog.cancel();
Dialog liveView = new Dialog(myView.this, R.style.Dialog);
liveView.setContentView(R.layout.liveview_dialogue);
TextView title = (TextView)liveView.findViewById(R.id.liveViewTitle);
Button button = (Button) liveView.findViewById(R.id.liveViewButton);
ImageView trackImage = (ImageView)liveView.findViewById(R.id.liveViewImage);
//I want to loop through the ten images here?
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
}
});
liveView.show();
}
}
