I have a code running inside the Thread. I tried to use the handler to do receive the message from the thread so i can update the UI. Unfortunately, the message didn't get send to the handler.
This is my code snippet inside the run method of the Thread
ChromaticLayout chromatic = new ChromaticLayout(mPartition, mDeviceWidth, mDeviceHeight, mData);
chromatic.execute(new ChromaticLayout.LayoutCallback() {
@Override
public synchronized void retrieveResult(Object[][] data) {
// TODO Auto-generated method stub
mPhotoData.clear();
Log.w("CALLBACK", "start");
for (int i=0; i<data.length; i++)
{
PhotoFrameData[] row = new PhotoFrameData[data[i].length];
for (int j=0; j<data[i].length; j++) {
if (j==0)
Log.w("CALLBACK", "Width = " + ((PhotoFrameData) data[i][j]).getRectangle().width() + " height = " + ((PhotoFrameData) data[i][j]).getRectangle().height() );
row[j] = (PhotoFrameData) data[i][j];
}
mPhotoData.add(row);
}
Log.w("CALLBACK", "end");
PhotoFrameAdapter.this.handle.post(new Runnable(){
@Override
public void run() {
// TODO Auto-generated method stub
PhotoFrameAdapter.this.handle.sendEmptyMessage(1);
} });
//if (!PhotoFrameAdapter.this.handle.sendEmptyMessage(1))
// Log.w("CALLBACK", "Handle not working");
}});
}
The is the receiving message of the handler:
protected Handler handle = new Handler() {
public void handleMessage(Bundle message) {
//PhotoFrameAdapter.this.notifyDataSetChanged();
mListener.dataLoaded(this);
}
};
What make it not adding to the message queue and call the handleMessage? Thanks
try this:
private Handler handler = new Handler() {
public void handleMessage(Message msg) {
switch (msg.what) {
case 1:
//do staff
break;
}
};
};
