Question

我的APP上有这个例外......我不知道为什么会发生这种情况。

java.lang.IllegalStateException： 适配器的内容已更改，但ListView未收到通知。确保不从后台线程修改适配器的内容，而只是从UI线程修改。

在ListView(2131492879)，类android.widget.ListView中使用适配器类com.agencialanave.AdaptadorListaApps

我尝试了很多选项，但我没有设法修复它。

类：Apps.java

public class Apps
{
    public Bitmap Colorbanda;
    public Bitmap Logo;
    public Bitmap LogoBasura;
    public String NombreAPP;
    public float MemoriaUsada;
    public String NombrePaquete;
    public File Apk;

    public Apps(Bitmap colorbanda, Bitmap logo,String nombreAPP, float memoriaUsada, Bitmap logoBasura, String nombrePaquete, File apk) 
    {
        super();
        Colorbanda = colorbanda;
        Logo = logo;
        LogoBasura = logoBasura;
        NombreAPP = nombreAPP;
        MemoriaUsada = memoriaUsada;
        NombrePaquete = nombrePaquete;
        Apk = apk;
    }

    public Apps(Bitmap colorbanda, Bitmap logo,String nombreAPP, float memoriaUsada, Bitmap logoBasura, String nombrePaquete) 
    {
        super();
        Colorbanda = colorbanda;
        Logo = logo;
        LogoBasura = logoBasura;
        NombreAPP = nombreAPP;
        MemoriaUsada = memoriaUsada;
        NombrePaquete = nombrePaquete;
    }

    public Bitmap getColorbanda() {
        return Colorbanda;
    }

    public void setColorbanda(Bitmap colorbanda) {
        Colorbanda = colorbanda;
    }

    public Bitmap getLogo() {
        return Logo;
    }

    public void setLogo(Bitmap logo) {
        Logo = logo;
    }

    public Bitmap getLogoBasura() {
        return LogoBasura;
    }

    public void setLogoBasura(Bitmap logoBasura) {
        LogoBasura = logoBasura;
    }

    public String getNombreAPP() {
        return NombreAPP;
    }

    public void setNombreAPP(String nombreAPP) {
        NombreAPP = nombreAPP;
    }

    public float getMemoriaUsada() {
        return MemoriaUsada;
    }

    public void setMemoriaUsada(float memoriaUsada) {
        MemoriaUsada = memoriaUsada;
    }

    public String getNombrePaquete() {
        return NombrePaquete;
    }

    public void setNombrePaquete(String nombrePaquete) {
        NombrePaquete = nombrePaquete;
    }

    public File getApk() {
        return Apk;
    }

    public void setApk(File apk) {
        Apk = apk;
    }
}

类：AdaptadorListaApps.java

public class AdaptadorListaApps extends ArrayAdapter<Apps>
{
    private static Activity Context;
    ArrayList<Apps> listaApps;

    public AdaptadorListaApps(Activity context, ArrayList<Apps> lista) 
    {
        super(context, R.layout.layout_list, lista);
        Context = context;

        listaApps = lista;
    }

    class ViewHolder
    {
        ImageView fotoBandaColor,fotoLogoApp,fotoDelete;
        TextView nombreApp, memoriaUsada;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {

        View item =convertView;
        ViewHolder holder;

        if (item == null)
        {

            LayoutInflater inflater = Context.getLayoutInflater();
            item = inflater.inflate(R.layout.layout_list, null);

            holder = new ViewHolder();

            holder.fotoBandaColor = (ImageView)item.findViewById(R.id.bandaColor);
            holder.fotoLogoApp = (ImageView)item.findViewById(R.id.logoApp);
            holder.fotoDelete = (ImageView)item.findViewById(R.id.borrarApp);
            holder.nombreApp = (TextView)item.findViewById(R.id.nombreApp);
            holder.memoriaUsada = (TextView)item.findViewById(R.id.memoriaUsada);

            item.setTag(holder);
        }
        else
        {
            holder=(ViewHolder) item.getTag();
        }

        holder.fotoBandaColor.setImageBitmap(listaApps.get(position).getColorbanda());
        holder.fotoLogoApp.setImageBitmap(listaApps.get(position).getLogo());
        holder.fotoDelete.setImageBitmap(listaApps.get(position).getLogoBasura());
        holder.memoriaUsada.setText(TamañoAppEnRam(listaApps.get(position).getMemoriaUsada()) + " MB  ( " + PorcentageMemoria(listaApps.get(position).getMemoriaUsada())+"% )");

        if(listaApps.get(position).getMemoriaUsada() < 4)
        {
            holder.memoriaUsada.setTextColor(Color.parseColor("#56E000"));
        }
        else if(listaApps.get(position).getMemoriaUsada() > 7)
        {
            holder.memoriaUsada.setTextColor(Color.RED);
        }                   
        else
        {
            holder.memoriaUsada.setTextColor(Color.parseColor("#FF8000"));
        }

        holder.nombreApp.setText(listaApps.get(position).getNombreAPP());


        return item;
    }
}

更新列表视图的代码

private class GetRunningApps extends AsyncTask<String, ArrayList<Apps>, String> 
    {
        @Override
        protected String doInBackground(String... params) throws IllegalStateException
        {

        }
    }

请帮助我......谢谢

您永远不应在后台线程上更改视图或其任何基础数据源的属性。

请勿操纵listaaps中的变量onBackground。只能在onPostExecute或onProgressUpdate。
请勿操纵adaptorLista中的变量onBackground。只能在onPostExecute或onProgressUpdate。

如何解决：适配器的内容已更改，但ListView未收到通知
