我是android开发的新手.我正在尝试在我的小部件中加载listview使用Web服务.它的负载完美,但我想根据我的要求动态更新我的列表视图.
这附上我的代码:
package com.widget;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.net.Uri;
import android.util.Log;
import android.widget.RemoteViews;
public class WidgetProvider extends AppWidgetProvider {
public static final String DATA_FETCHED = "com.widget.DATA_FETCHED";
public static String UPDATE_LIST = "UPDATE_LIST";
AppWidgetManager appWidgetManager;
ComponentName currentWidget;
public static Integer randomNumber;
SharedPreferences sharedprefer;
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
final int N = appWidgetIds.length;
for (int i = 0; i < N; i++) {
Intent serviceIntent = new …我在listfragment中有错误"FragmentTransaction类型中的方法replace(int,Fragment)不适用于参数(int,ListFragment)"我该怎么办？因为我不能出现我的片段.
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends Activity {
private FadingActionBarHelper mFadingActionBarHelper;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mFadingActionBarHelper = new FadingActionBarHelper(getActionBar(),
getResources().getDrawable(R.drawable.actionbar_bg));
if (savedInstanceState == null) {
getFragmentManager().beginTransaction()
.add(R.id.container, new ListViewFragment())
.commit();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
} …
