如何更改列表視圖的文本顏色

Question

好，所以使用textView的技巧不適用於此。 所以我知道這已經很簡單了....對吧？ 因爲我可能會幫助我在稍後添加圖片。

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/logo" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    > 

    <ListView 
     android:id="@android:id/list" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignLeft="@+id/textView1" 
     android:layout_alignParentBottom="true" 
     android:layout_below="@+id/textView1" 
     android:paddingLeft="8dp" 
     android:paddingRight="8dp" > 

    </ListView> 

    <TextView 
     android:id="@+id/textView1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:text="@string/welcome" 
     android:textColor="#b70000" 
     android:textSize="16sp" /> 

</RelativeLayout> 

我用它來調用它並添加到java代碼中的listview。

       "Haunted House", 
       "Amy's Nightmare", 
       "Zombie Town", 
       "Haunted Hayride", 
       "Quit"

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

     //found this part on an example 
     //Set up ArrayAdaptor for the options 
     setListAdapter(new ArrayAdapter<String> 
      (this, android.R.layout.simple_list_item_1, CHOICES)); 
     getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE); 
     getListView().setTextFilterEnabled(true); 

     //part of example 
     //Set up the listener for user clicks on the list 
     setListClickListener(); 

     //this toast is for when it opens 
     Toast.makeText(this, "I see your fear...", Toast.LENGTH_SHORT).show(); 
    }

          default: break; 
         } 
        } 
       }//END OnItemClickListener 
      );//END setOnItemClickListener 
     }//END setListClickListener 

    //goes to haunted house

      startActivity(launchnightmare); 

     }//END launchNightmarePage 

    //goes to Amy's Nightmare 
    protected void launchZombiePage() 
     { 
      //Set up Intent 
      Intent launchzombies = new Intent(this, ZombieTownList.class); 
      startActivity(launchzombies); 

     }//END launchZombiePage 

    //goes to haunted house

     { 
      //Set up Intent 
      Intent launchhayride = new Intent(this, HauntedHayrideList.class); 
      startActivity(launchhayride); 

     }//END launchHayridePage 
} 

Answer 1

您已經指定了使用內置的適配器（ArrayAdapter）項目佈局android.R.layout.simple_list_item_1。

如果您需要自定義佈局，您可以將Android SDK中的simple_list_item_1.xml佈局（查看platforms/android-18/data/res/layout文件夾）複製到您的項目中並對其進行修改。例如，您將其稱爲my_simple_list_item_1.xml。

然後修改代碼以使用您的佈局，而不是android.R.layout.simple_list_item_1：

setListAdapter(new ArrayAdapter<String>(this, R.layout.my_simple_list_item_1, CHOICES)); 

你會看到，機器人會simple_list_item_1管理佈局只是一個TextView的，你可以添加textColor屬性，並根據自己的喜好進行修改。
