我正在开发一个带有使用Fragments的菜单的简单WebView应用程序,一切正常,但ListView上的文本是黑色的,我不知道如何改变它。
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" />
默认文字颜色是黑色但我想将其更改为白色,我该怎么办? 提前致谢

另一种最简单的方法是使用textSize,textStyle,color等创建一个包含所需textview的布局文件,然后将其与ArrayAdapter一起使用。
e.g。 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ArrayAdapter一起使用,如
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);

不要使用android.R.layout.simple_list_item_activated_1
作为ArrayAdapter
内部行的模板,而是创建自己的行xml
文件并在其中设置文字颜色:
<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>

不要使用xml布局文件系统,你应该编写自己的xml布局,然后引用它,但你可以直接在你的布局里写一下来修改任何文字的颜色。
