如何更改ListView项目的文本颜色?

出于某种原因, 我似乎无法更新我的ListView项目中的文本的颜色 。 我不确定这是为什么发生,有没有人有一个想法?

XML:

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ListView android:id="@+id/listView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:textColor="@android:color/white" android:textSize="20sp"> </ListView> </RelativeLayout> 

JAVA:

 public class MainActivity extends Activity { Context context; ArrayList<String> aa = new ArrayList<String>(); ListView lv; final String URL = "http://news.google.com"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setContentView(R.layout.activity_main); setContentView(R.layout.splash); lv= (ListView) findViewById(R.id.listView1); new MyTask().execute(URL); } private class MyTask extends AsyncTask<String, Void, String> { ProgressDialog prog; String title = ""; @Override protected void onPreExecute() { prog = new ProgressDialog(MainActivity.this); prog.setMessage("Loading...."); prog.show(); } @Override protected String doInBackground(String... params) { try { Document doc = Jsoup.connect(params[0]).get(); Element tableHeader = doc.select("tr").first(); for (Element element : tableHeader.children()) { aa.add(element.text().toString()); } title = doc.title(); } catch (IOException e) { e.printStackTrace(); } return title; } @Override protected void onPostExecute(String result) { super.onPostExecute(result); prog.dismiss(); ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,aa); lv.setAdapter(adapter); } } } 

编辑(回复Philipp Jahoda的回答):

  @Override protected void onPostExecute(String result) { super.onPostExecute(result); prog.dismiss(); ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.custom_textview, aa); setContentView(R.layout.activity_main); lv = (ListView) findViewById(R.id.listView1); lv.setAdapter(adapter); } }

Solutions Collecting From Web of "如何更改ListView项目的文本颜色?"

您需要为您的ListView项目创build一个自定义布局 ,并在其中设置所需的文本颜色。

这样,你甚至不需要一个自定义适配器。

例如custom_textview.xml

 <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tv" android:textColor="@color/white" android:layout_width="fill_parent" android:gravity="center" android:layout_height="fill_parent"/> 

然后,您可以使用您的布局与ArrayAdapter

 ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.custom_textview, aa); lv.setAdapter(adapter); 

这是因为android.R.layout.simple_list_item_1使用默认的文本颜色,所以最好的方法是通过自己的xml如下所示:

 < TextView android:id="@android:id/text1" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:textColor="@android:color/white" android:textSize="16sp" /> 

我有相同的任务,我只需要将文本颜色更改为白色(因为我有一个黑暗的背景图像),但想保持默认的“simple_list_item_1”布局。

上面的答案弄乱了我的布局,所以我search了原始布局的xml,并在最后添加了android:textColor="@android:color/white"

 <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/text1" android:layout_width="match_parent" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceListItemSmall" android:gravity="center_vertical" android:paddingStart="?android:attr/listPreferredItemPaddingStart" android:paddingEnd="?android:attr/listPreferredItemPaddingEnd" android:paddingLeft="?android:attr/listPreferredItemPaddingLeft" android:paddingRight="?android:attr/listPreferredItemPaddingRight" android:minHeight="?android:attr/listPreferredItemHeightSmall" android:textColor="@android:color/white" /> 

XML基础: https : //github.com/android/platform_frameworks_base/blob/master/core/res/res/layout/simple_list_item_1.xml

试试android:textColor="#FFFFFF"来代替。
