几个小时的研究后,我终于正式的咨询帮助。 为什么不onHandleIntent()
被调用? 有什么问题吗?
在主要活动onCreate()
mService = new Intent(context, xyz.class);
startService(mService);
这ISS它。 该onStartCommand()
被调用,而不是onHandleIntent()
package com.autoalbumwallaperplus;
import android.app.IntentService;
import android.content.Intent;
import android.widget.Toast;
public class xyz extends IntentService {
public xyz() {
super("bmp");
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this,"onStartCommand works!", Toast.LENGTH_SHORT).show();
return super.onStartCommand(intent,flags,startId);
}
@Override
protected void onHandleIntent(Intent workIntent) {
Toast.makeText(this,"onHandleIntent works!", Toast.LENGTH_SHORT).show();
}
}
这是OnHandleIntent内
String imagepath = workIntent.getStringExtra("String");
Toast.makeText(this, "it works" , Toast.LENGTH_SHORT).show();
DisplayMetrics displayMetrics = new DisplayMetrics();
WindowManager hi = ((WindowManager) getBaseContext().getSystemService(Context.WINDOW_SERVICE));
int height = displayMetrics.heightPixels;
int width = displayMetrics.widthPixels << 2;
// ... First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
Bitmap decodedSampleBitmap = BitmapFactory.decodeFile(imagepath, options);
// ... Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, width, height);
// ... Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
decodedSampleBitmap = BitmapFactory.decodeFile(imagepath, options);
// ... Set Wallpaper
//Context context = getApplicationContext();
WallpaperManager wm = WallpaperManager.getInstance(this);
try {
wm.setBitmap(decodedSampleBitmap);
} catch (IOException e) {
}
