我有一个典型的场景 - 主 (ListFragment) Activity ,它在项目点击时触发详细 Activity 。一切正常。
现在我想根据编程条件制作详细 View (红色/绿色)中的所有文本。我知道这样做的方法是使用主题
因此在 values-v14 中(我的三星 Note 1 设备运行的是 android 4.1), 样式.xml
<style name="ExpensesStyle" parent="@android:style/TextAppearance.Medium">
<item name="android:textColor">@color/expense_background</item>
</style>
颜色.xml
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<color name="credit_background">#6DA000</color>
<color name="expense_background">#D30A0A</color>
</resources>
androidManifest.xml
<activity
android:name="com.app.transactions.TransactionActivity"
android:label="@string/app_name"
android:theme="@style/ExpensesStyle">
</activity>
android:theme 属性导致以下崩溃。将样式应用于单个 View (EditText) 可以正常工作。

Activity.onCreate
@Override
protected void onCreate(Bundle instanceState) {
try {
super.onCreate(instanceState);
setContentView(R.layout.activity_simple);
Intent intent = getIntent();
long transId = intent.getLongExtra(EXTRA_TRAN_ID, 0);
boolean isExpense = intent.getBooleanExtra(EXTRA_TRAN_IS_EXPENSE, true);
if(instanceState != null)
return;
Fragment frag = TransactionDetailFragment.newInstance(isExpense ? new ExpenseFragment(): new CreditFragment(),
transId, this);
getSupportFragmentManager().beginTransaction()
.add(R.id.simple_fragment_container, frag)
.commit();
} catch (Exception e) {
Log.e(TAG, "Error in creation Tran Detail Activity", e);
}
}
layout.activity_simple 是一个带有 fragment 占位符的简单框架布局。
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/simple_fragment_container" />
fragment 布局的第30行包含
<TextView
style="?android:listSeparatorTextViewStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/label_category" />
最佳答案
style="?android:listSeparatorTextViewStyle"
未在 parent="@android:style/TextAppearance.Medium"
View 使用的所有参数都必须在您的样式或父样式中定义。
编辑:
要回答您真正的问题(如何使这些样式起作用),请引用以下方向:
创建您的编辑文本样式:
<style name="MyApp_EditText_style" parent="android:Widget.EditText">
// those below are all the items you CAN change,
// but you should only change those that you really need.
<item name="android:focusable">___value___</item>
<item name="android:focusableInTouchMode">___value___</item>
<item name="android:clickable">___value___</item>
<item name="android:background">___value___</item>
<item name="android:textAppearance">___value___</item>
<item name="android:textColor">___value___</item>
<item name="android:gravity">___value___</item>
</style>
然后在您的 Activity 或 Application 样式上添加编辑文本
<style name="MyApp.Theme" parent="@android:style/Theme.Holo">
<item name="android:editTextStyle">@style/MyApp_EditText_style</item>
</style>
请注意, Activity 或应用程序样式 parent
必须是主要的 Android theme
之一,例如 HOLO、HOLO.LIGHT、Theme.Light,或其中之一的后代
