嵌入的RatingBar在AlertDialog

Question

我有一個ListView包含的RatingBar指示的東西，如果你點擊它彈出一個對話框（AlertDialog）的LisView的項目包括的RatingBar，現在我不知道：

1. 如何風俗在對話框中顯示的RatingBar（下面的代碼不起作用，我認爲它是因爲最後的，這使得它不能被定製）。
2. 如何將評分從對話框RatingBar傳遞給ListView RatingBar。

我當前的代碼是：

final RatingBar ratingBar = new RatingBar(getApplicationContext()); 
ratingBar.setRating(0); 
ratingBar.setStepSize(1); 
ratingBar.setNumStars(2); 
builder.setTitle(R.string.alertdialog_title) 
.setIcon(android.R.drawable.ic_dialog_info) 
.setView(ratingBar) 
.setPositiveButton("Submit", new DialogInterface.OnClickListener() { 
    public void onClick(DialogInterface dialog, int which) { 
     // do something. 
    } 
})    
.setNegativeButton("Cancel", null); 

EDIT1
我已經表現出對列表視圖與fileListAdapter（FileListAdapater的實例作爲代碼1）項的評級。現在的問題是：在對話框中點擊

1. 該評級變化之後，但它不是，我點擊，如何地圖與評級（位於對話框），更改的項目的項目。
2. 如何存儲評分，每次ListView刷新時，評分都會消失。

我已經把onItemClickListener的對話框代碼設置爲code2。
代碼1：

public class FileListAdapter extends BaseAdapter { 
private Context context; 
private ArrayList<File> files; // The ArrayList to store the files 
private boolean isSDcard; // To indicate whether the file is the SDcard 
private LayoutInflater mInflater; // The LayoutInflater 

public FileListAdapter (Context context, ArrayList<File> files, boolean isSDcard) { 
    this.context = context; 
    this.files = files; 
    this.isSDcard = isSDcard; 
    mInflater = LayoutInflater.from(context); 
} 

@Override 
public int getCount() { 
    return files.size(); 
} 

@Override 
public Object getItem (int position) { 
    return files.get(position); 
} 

@Override 
public long getItemId (int position) { 
    return position; 
} 

@Override 
public View getView (int position, View convertView, ViewGroup parent) { 
    ViewHolder viewHolder; 
    /** 
    * The view is not initialized,initialize the view according to the layout file, 
    * and bind it to tag. 
    */ 
    if(convertView == null) { 
     viewHolder = new ViewHolder(); 
     convertView = mInflater.inflate(R.layout.file_list_item, null); // Inflate from the layout file 
     convertView.setTag(viewHolder); 
     viewHolder.file_title = (TextView) convertView.findViewById(R.id.file_title); // Find the file_title textview 
     viewHolder.file_icon = (ImageView) convertView.findViewById(R.id.file_icon); // Find the file_icon imageview 
     viewHolder.file_path = (TextView) convertView.findViewById(R.id.file_path); // Find the file_path textview 
     viewHolder.encrypt_level = (RatingBar) convertView.findViewById(R.id.encrypt_level); // Find the rating_bar view 
    } else { 
      viewHolder = (ViewHolder) convertView.getTag(); 
    } 
    File file = (File) getItem(position); 
    if(position == 0 && !isSDcard) { // Add the back to SDcard item 
     viewHolder.file_title.setText(R.string.back_to_sdcard); 
     viewHolder.file_icon.setImageResource(R.drawable.sdcard_icon); 
     viewHolder.file_path.setText(Environment.getExternalStorageDirectory().toString()); 
     viewHolder.encrypt_level.setRating(0); 
    } 
    if(position == 1 && !isSDcard) { // Add the back to parent item 
     viewHolder.file_title.setText(R.string.back_to_parent); 
     viewHolder.file_icon.setImageResource(R.drawable.folder_up_icon); 
     viewHolder.file_path.setText(file.getPath()); 
     viewHolder.encrypt_level.setRating(0); 
    } else { // The current filepath is the SDcard or the position is neither 0 nor 1 
      String fileName = file.getName(); 
      viewHolder.file_title.setText(fileName); 
      viewHolder.file_path.setText(file.getPath()); 
      viewHolder.encrypt_level.setRating(0); 
      if(file.isDirectory()) { // The variable file is a directory 
       viewHolder.file_icon.setImageResource(R.drawable.folder_icon); 
      } else { // The variable file is a file 
       viewHolder.file_icon.setImageResource(R.drawable.file_icon); 
      } 
     } 

return convertView; 
} 
    private class ViewHolder { 
     private ImageView file_icon; // The icon of the file 
    private TextView file_title; // The title of the file 
    private TextView file_path; // The path of the file 
    private RatingBar encrypt_level; // The encrypt level of the file 
    } 
} 

碼2：

final Dialog rankDialog = new Dialog(MainActivity.this, R.style.FullHeightDialog); 
rankDialog.setContentView(R.layout.rank_dialog); 
rankDialog.setCancelable(true); 
final RatingBar ratingBar = (RatingBar)rankDialog.findViewById(R.id.dialog_ratingbar); 

TextView text = (TextView) rankDialog.findViewById(R.id.rank_dialog_text1); 
text.setText("Set Rating!"); 

Button updateButton = (Button) rankDialog.findViewById(R.id.rank_dialog_button); 
updateButton.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     Log.d(Tag, ratingBar.getRating() + ""); 
     RatingBar ratebar = (RatingBar) findViewById(R.id.encrypt_level); // The RatingBar in the ListView. 
    ratebar.setRating(ratingBar.getRating()); // Change the rating. 
    rankDialog.dismiss(); 
} 
}); 
rankDialog.show(); 

Answer 1

嘗試定製與評價欄對話框。

像

Button rankBtn = (Button) findViewById(R.id.rank_button); 
rankBtn.setOnClickListener(new View.OnClickListener() { 
    public void onClick(View v) { 
     rankDialog = new Dialog(MyActivity.this, R.style.FullHeightDialog); 
     rankDialog.setContentView(R.layout.rank_dialog); 
     rankDialog.setCancelable(true); 
     ratingBar = (RatingBar)rankDialog.findViewById(R.id.dialog_ratingbar); 
     ratingBar.setRating(userRankValue); 

     TextView text = (TextView) rankDialog.findViewById(R.id.rank_dialog_text1); 
     text.setText(name); 

     Button updateButton = (Button) rankDialog.findViewById(R.id.rank_dialog_button); 
     updateButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       rankDialog.dismiss(); 
      } 
     }); 
     //now that the dialog is set up, it's time to show it  
     rankDialog.show();     
    } 
}); 

，這裏是佈局/ rank_dialog.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    android:padding="2dip"> 

    <TextView android:text="Doctor's Name" android:id="@+id/rank_dialog_text1" 
     android:textSize="24dp" android:layout_marginTop="10dp" 
     android:layout_width="wrap_content" android:layout_height="wrap_content" 
     android:layout_gravity="center"/> 

    <RatingBar 
     android:layout_marginTop="10dp" android:layout_marginBottom="10dp" 
     android:layout_width="wrap_content" android:layout_height="wrap_content" 
     android:clickable="true" 
     android:id="@+id/dialog_ratingbar" android:layout_gravity="center" 
     android:numStars="5" android:stepSize="1.0" android:rating="2" 
     android:isIndicator="false"/> 

    <Button android:id="@+id/rank_dialog_button" 
     android:layout_height="wrap_content" 
     android:text="Update" android:focusable="false" 
     android:layout_margin="5dip" android:textColor="#FFF8C6" 
     android:textSize="20dip" android:layout_width="fill_parent" /> 

</LinearLayout> 

值/ my_style.xml

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <style name="FullHeightDialog" parent="android:style/Theme.Dialog"> 
    <item name="android:windowNoTitle">true</item> 
    </style> 
</resources>
