突出顯示的ListView所選擇的行的Android

我已創建一個ListView一套我已成功地成功地交替的顏色的行。突出顯示的ListView所選擇的行的Android

不過，我希望能夠一旦用戶選擇了一個改變行的顏色。

我已經把我的XML如下：

<ListView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:layout_alignParentTop="true" 
    android:layout_alignParentStart="true" 
    android:id="@+id/listView" 
    android:listSelector="@android:color/holo_red_light"/>

我的完整的Java代碼如下：

public class Task2Activity extends ListActivity { 

ListView list; 
String [] dogTitles; 
String [] dogDescriptions; 
String [] dogToastDescriptions; 
int[] images = {R.drawable.husky, R.drawable.pug, R.drawable.yorkshire_terrier, R.drawable.french_bulldog, 
R.drawable.border_collie, R.drawable.great_dane, R.drawable.staffordshire_bull_terrier, R.drawable.golden_retriever, 
R.drawable.german_shepherd, R.drawable.doberman}; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    //setContentView(R.layout.activity_task2); 

    Resources res = getResources(); 
    dogTitles = res.getStringArray(R.array.titles); 
    dogDescriptions = res.getStringArray(R.array.descriptions); 
    dogToastDescriptions = res.getStringArray(R.array.toastdescriptions); 



    //list = (ListView) findViewById(R.id.listView); 
    dogAdapter <String> adapter = new dogAdapter<String>(this, dogTitles, images, dogDescriptions) { 
     //list. 

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

      View view = super.getView(position, convertView, parent); 
      if (position %2 == 1) 
      { 
       view.setBackgroundColor(Color.parseColor("#e6e9ef")); 
      } 
      else 
      { 
       view.setBackgroundColor(Color.parseColor("#c9d0db")); 
      } 
      return view; 

     } 
    }; 

    setListAdapter(adapter); 

    registerForContextMenu(getListView()); 

     } 

    @Override 
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) { 
    super.onCreateContextMenu(menu, v, menuInfo); 

    MenuInflater menuInflater = getMenuInflater(); 
    menuInflater.inflate(R.menu.my_context_menu, menu); 

} 

protected void onListItemClick(ListView l, View v, int position, long id){ 

    String item = dogToastDescriptions[position]; 


     Toast.makeText(this, item, Toast.LENGTH_LONG).show(); 
    getListView().setSelected(true); 


     } 

class dogAdapter<S> extends ArrayAdapter<String> { 
Context context; 
int[] images; 
String[] titleArray; 
String[] descriptionArray; 

dogAdapter(Context c, String[] titles, int imgs[], String[] desc) { 
    super(c, R.layout.single_row, R.id.largeText, titles); 
    this.context = c; 
    this.images = imgs; 
    this.titleArray = titles; 
    this.descriptionArray = desc; 
} 

class MyViewHolder { 
    ImageView myImage; 
    TextView myTitle; 
    TextView myDescription; 

    MyViewHolder(View v) { 
     myImage = (ImageView) v.findViewById(R.id.imageView); 
     myTitle = (TextView) v.findViewById(R.id.largeText); 
     myDescription = (TextView) v.findViewById(R.id.smallText); 
    } 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    View row = convertView; 
    MyViewHolder holder = null; 
    if (row == null) { 
     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     row = inflater.inflate(R.layout.single_row, parent, false); 
     holder = new MyViewHolder(row); 
     row.setTag(holder); 
     Log.d("dogs", "Creating a new row"); 
    } else { 
     holder = (MyViewHolder) row.getTag(); 
     Log.d("dogs", "Recycling stuff"); 
    } 
    //ImageView myImage = (ImageView) row.findViewById(R.id.imageView); 
    //TextView myTitle = (TextView) row.findViewById(R.id.largeText); 
    //TextView myDescription = (TextView) row.findViewById(R.id.smallText); 

    holder.myImage.setImageResource(images[position]); 
    holder.myTitle.setText(titleArray[position]); 
    holder.myDescription.setText(descriptionArray[position]); 

    return row; 
} 

} 
}

任何幫助極大的讚賞。非常感謝

你得到的答案？ – sivaram

在onListItemClick（），您可以設置所選項目的顏色：

protected void onListItemClick(ListView l, View v, int position, long id){ 

    String item = dogToastDescriptions[position]; 

    v.setBackgroundColor(ContextCompat.getColor(this, android.R.color.holo_green_light));//your color here 

    Toast.makeText(this, item, Toast.LENGTH_LONG).show(); 
    getListView().setSelected(true); 

}

還有在ListView的選項，突出選擇的值：

<ListView android:id="@+id/my_listView" 
    android:choiceMode="singleChoice" 
    android:listSelector="@android:color/darker_gray" <!--your color here --> 
    />

機器人： choiceMode =「singleChoice」是你在找什麼

謝謝你。它確實起作用，因爲它突出顯示了我點擊的那一行，但是當我點擊另一行時它會保持突出顯示。換句話說，我不斷點擊行並繼續突出顯示它們。我希望它能夠突出顯示一個，然後在我點擊另一個時突出顯示另一個。謝謝 –

@PhilAdams，您應該存儲最後一次突出顯示的單擊片段的位置，並將其更改回原始顏色，然後將新選擇的項目更改爲突出顯示的顏色。 –

@BradleyWilson感謝您的建議。我不太清楚該怎麼做，但我會查找它，並給它一個 –
