问题
I have a list with a complex layout R.layout.menu_row
. It consists of a ProgressBar
and a text field. The adapter I use:
SimpleAdapter simpleAdapter = new SimpleAdapter(this, getData(path),
R.layout.menu_row, new String[] { "title", "progress" },
new int[] { R.id.text1,R.id.progressBar1});
The adapter knows how to handle TextViews
by it self but not ProgressBars
, so I wrote a complex data binder:
SimpleAdapter.ViewBinder viewBinder = new SimpleAdapter.ViewBinder() {
@Override
public boolean setViewValue(View view, Object data, String textRepresentation) {
//here goes the code
if () {
return true;
}
return false;
}
Now I'm stuck filling the mapping inside the function. I need to set the value of string progress
to the setProgress
method of the ProgressBar
. But I don't get a handle to string progress
and to the ProgressBar
.
回答1:
You need to find out if the ViewBinder
is called for the ProgressBar
and set its progress(from the data
parameter(the data from column progress
in your case)):
SimpleAdapter.ViewBinder viewBinder = new SimpleAdapter.ViewBinder() {
@Override
public boolean setViewValue(View view, Object data, String textRepresentation) {
if (view.getId() == R.id.progressBar1) {
// we are dealing with the ProgressBar so set the progress and return true(to let the adapter know you binded the data)
// set the progress(the data parameter, I don't know what you actually store in the progress column(integer, string etc)).
return true;
}
return false; // we are dealing with the TextView so return false and let the adapter bind the data
}
EDIT :
I've seen in your addItem
method that you do:
temp.put("progress", name);// Why do you set again the name as progress?!?
I think what you should set here is the progress
parameter:
temp.put("progress", progress);
Then in the ViewBinder
:
if (view.getId() == R.id.progressBar1) {
Integer theProgress = (Integer) data;
((ProgressBar)view).setProgress(theProgress);
return true;
}
