我允许用户通过发送包含来自用户图库的图像的请求代码来更改 Personalize 类中的图标。setIconImageinWidget() 方法将结果发送到此处（在 Drag_and_Drop_App 中）：

     else if(requestCode == RESULT_ICON){
         byte[] byteArray = data.getByteArrayExtra("myIconBitmap"); 
         Bitmap myIcon = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length); 
         setBackgroundImageForIcon(myIcon); 
         Log.d("Drag_and_Drop_App", "Icon is set");
     }
     }

这是 setBackgroundImageForIcon 方法：

         @SuppressLint("NewApi") 
     private void setBackgroundImageForIcon(Bitmap bitmap) { 
     ImageView ivICON = (ImageView) findViewById(R.id.bwidgetOpen);

     Drawable dq = new BitmapDrawable(getResources(), bitmap); 

     if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) { 
     ivICON.setImageDrawable(dq);
     } else { 
     ivICON.setImageDrawable(dq);
     Log.d("Drag_and_Drop_App", "Icon is set");
     } 
     }

这不会返回任何错误，但图标根本不会根据用户选择使用的任何图片而更改。

看了一会儿后，我意识到我必须在这里更改我的编码的应用程序小部件提供程序部分：

package com.example.awesomefilebuilderwidget;
IMPORTS
public class AFBWidget extends AppWidgetProvider{

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) {
    // TODO Auto-generated method stub
    super.onUpdate(context, appWidgetManager, appWidgetIds);
    Random r = new Random();
    int randomInt = r.nextInt(1000000000);
    String rand = String.valueOf(randomInt);

    final int N = appWidgetIds.length;

    for (int i = 0; i < N; i++){
        int awID = appWidgetIds[i];
        RemoteViews v = new RemoteViews(context.getPackageName(), R.layout.widget);
        v.setTextViewText(R.id.tvwidgetUpdate, rand);
           Intent configIntent = new Intent(context, Drag_and_Drop_App.class);

            PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, PendingIntent.FLAG_UPDATE_CURRENT);

            v.setOnClickPendingIntent(R.id.bwidgetOpen, configPendingIntent);
           //me trying to set the Bitmap from the above classes somehow... v.setImageViewBitmap(R.id.bwidgetOpen, R.id.);

        appWidgetManager.updateAppWidget(awID, v);
    }

}

@Override
public void onDeleted(Context context, int[] appWidgetIds) {
    // TODO Auto-generated method stub
    super.onDeleted(context, appWidgetIds);
    Toast.makeText(context, "Thanks for checking us out!", Toast.LENGTH_SHORT).show();
}
}

我正在更改的 imageView 是这样的：

<ImageView
    android:id="@+id/bwidgetOpen"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_launcher"
    android:contentDescription="@string/desc"/>

在 Widget.xml 中

如何更改我的 Widget Provider 以允许更改图标？我知道这需要阅读很多内容，但需要任何帮助！

更新：

         @SuppressLint("NewApi") 
     private void setBackgroundImageForIcon(Bitmap bitmap) { 
         Log.d("Drag_and_Drop_App", "Icon...");
     ImageView ivICON = (ImageView) findViewById(R.id.bwidgetOpen);

     BitmapDrawable dq = new BitmapDrawable(getResources(), bitmap); 

     if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) { 
     // ivICON.setImageDrawable(dq);
         ivICON.setImageResource(R.drawable.pattern1);
     } else { 
    // ivICON.setImageDrawable(dq);
     ivICON.setImageResource(R.drawable.pattern1);
     Log.d("Drag_and_Drop_App", "Icon is set");
     } 
     }
