更改 android 数组适配器中的列表项颜色
Changing the list item color in android Array Adapter
我正在使用 Fragments 开发一个带有菜单的简单 WebView 应用程序，一切正常，但 ListView 上的文本是黑色的，我不知道如何更改它。
我想知道如何更改列表视图的文本颜色...这是我的代码：
package com.lfcchile;
private ActionBarDrawerToggle actionBarDrawerToggle;
private ActionBar actionBar;
private DrawerLayout drawerLayout;
private ListView navList;
private FragmentTransaction fragmentTransaction;
private FragmentManager fragmentManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setIcon(R.mipmap.ic_launcher);
drawerLayout = (DrawerLayout) findViewById(R.id.drawerlayout);
navList = (ListView) findViewById(R.id.navList);
ArrayList<String> navArray = new ArrayList<String>();
navArray.add("Inicio");
navArray.add("Destacado");
navArray.add("Tabla PL");
navArray.add("Próximo Partido");
navArray.add("Fragment 4");
navArray.add("Fragment 5");
navList.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_activated_1, navArray);
navList.setAdapter(adapter);
navList.setOnItemClickListener(this);
actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.opendrawer, R.string.closedrawer);
drawerLayout.setDrawerListener(actionBarDrawerToggle);
//ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
fragmentManager = getSupportFragmentManager();
loadSelection(0);
}
private void loadSelection(int i){
navList.setItemChecked(i, true);
switch (i){
case 0:
HomeFragment homeFragment = new HomeFragment();
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragmentholder,homeFragment);
fragmentTransaction.commit();
break;
case 1:
MyFragment1 myFragment1 = new MyFragment1();
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragmentholder,myFragment1);
fragmentTransaction.commit();
break;
case 2:
MyFragment2 myFragment2 = new MyFragment2();
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragmentholder,myFragment2);
fragmentTransaction.commit();
break;
case 3:
MyFragment3 myFragment3 = new MyFragment3();
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragmentholder,myFragment3);
fragmentTransaction.commit();
break;
case 4:
break;
case 5:
break;
}
}
@Override
public void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
actionBarDrawerToggle.syncState();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
} else if (id == android.R.id.home) {
if (drawerLayout.isDrawerOpen(navList)) {
drawerLayout.closeDrawer(navList);
} else {
drawerLayout.openDrawer(navList);
}
}
return super.onOptionsItemSelected(item);
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
loadSelection(position);
drawerLayout.closeDrawer(navList);
}
这是我的XML
<android.support.v4.widget.DrawerLayout 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:id="@+id/drawerlayout"
>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/fragmentholder"
>
</FrameLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/navList"
android:divider="@null"
android:layout_gravity="start"
android:backgroundTint="#8a0000"
android:background="#8a0000" />
默认的文字颜色是黑色，但我想把它改成白色，怎么办？

不要使用 android.R.layout.simple_list_item_activated_1 作为 ArrayAdapter 中行的模板，而是创建自己的行 xml 文件并在其中设置文本颜色：
<LinearLayout
android:width="match_parent"
android:height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="row_text_view"
android:textColor="#00ff00"
android:width="wrap_content"
android:height="wrap_Content" />
</LinearLayout>
另一种最简单的方法是创建一个布局文件，其中包含您想要的文本视图以及您喜欢的 textSize、textStyle、color 等，然后将其与 ArrayAdapter 一起使用。
例如mytextview.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/font_content"
android:padding="5sp"
android:layout_width="fill_parent"
android:background="@drawable/rectgrad"
android:singleLine="true"
android:gravity="center"
android:layout_height="fill_parent"/>
然后像往常一样将它与您的 ArrayAdapter 一起使用
private ListView navList;
navList = (ListView) findViewById(R.id.navList);
ArrayList<String> navArray = new ArrayList<String>();
navArray.add("Inicio");
navArray.add("Destacado");
navArray.add("Tabla PL");
navArray.add("Próximo Partido");
navArray.add("Fragment 4");
navArray.add("Fragment 5");
ArrayAdapter<String> ad = new ArrayAdapter<String>(context,R.layout.mytextview,navArray);
navList.setAdapter(ad);
你不要用系统提供的xml布局文件，你应该自己写一个xml布局，然后去引用它，而你就可以直接在你写的布局里面任意去修改文字的颜色。
Do not use xml layout file system, you should write your own xml layout, then to refer to it, but you can write in your layout inside straight to modify the color of any text.
