How to set EditText style from styles.xml in Android?
问题
我正在生成EditText字段，并希望从styles.xml文件设置其样式。但是无法成功。我可以设置一些参数，但我更愿意使用styles.xml中的样式，这样以后如果需要更改会更容易。
styles.xml
<style name="input_fields_single_line"><item name="android:padding">8dp</item><item name="android:background">@drawable/input_field_shape</item><item name="android:maxLines">1</item></style>
Java代码:
List<EditText> inputFieldList = new ArrayList<EditText>();public void generateInputFields() {EditText editTextFieldTitle = new EditText(this);inputFieldList.add(editTextFieldTitle);editTextFieldTitle.setHint(R.string.enter_field_title);editTextFieldTitle.setMaxLines(1);editTextFieldTitle.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));editTextFieldTitle.setFocusableInTouchMode(true);editTextFieldTitle.requestFocus();editTextFieldTitle.setStyle(R.style.input_fields_single_line); // 使用样式myLayout.addView(editTextFieldTitle);}

I'm generating EditText fields and wish to set it's style from styles.xml file. But can't manage to do it. I can set some parameters, but I would rather use a style from styles.xml so it would be easier to change later if needed.
styles.xml
<style name="input_fields_single_line"><item name="android:padding">8dp</item><item name="android:background">@drawable/input_field_shape</item><item name="android:maxLines">1</item></style>
Java code:
List<EditText> inputFieldList = new ArrayList<EditText>();public void generateInputFields() {EditText editTextFieldTitle = new EditText(this);inputFieldList.add(editTextFieldTitle);editTextFieldTitle.setHint(R.string.enter_field_title);editTextFieldTitle.setMaxLines(1);editTextFieldTitle.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));editTextFieldTitle.setFocusableInTouchMode(true);editTextFieldTitle.requestFocus();myLayout.addView(editTextFieldTitle);}

你可以为 EditText 创建一个单独的样式，类似于你正在做的，但将其父级设置为 Widget.EditText，代码如下：
<style name="MyCustomeEditTextStyle" parent="@android:style/Widget.EditText">...根据需要添加项目<item name="android:padding">8dp</item><item name="android:background">@drawable/input_field_shape</item><item name="android:maxLines">1</item></style>
然后在 XML 中的每个编辑框中调用你的样式，如下所示：
<EditTextandroid:id="@+id/editTextId"android:layout_width="wrap_content"android:layout_height="wrap_content"style="@style/MyCustomeEditTextStyle" />
但是，如果你想要全局设置一次，并且由于你是以编程方式生成 EditText，类似于以下方式：
EditText editTextFieldTitle = new EditText(this);
那么你可以在应用程序样式中设置你的样式，如下所示：
<style name="AppTheme" parent="@android:style/YourParentTheme"><item name="android:editTextStyle">@style/MyCustomeEditTextStyle</item></style>
英文:
You create a separate style for the EditText like what you are doing but parented with the Widget.EditText like the following:
<style name="MyCustomeEditTextStyle" parent="@android:style/Widget.EditText">...add as many items as you need<item name="android:padding">8dp</item><item name="android:background">@drawable/input_field_shape</item><item name="android:maxLines">1</item></style>
Then call your style inside each edit text in the xml like the following:
<EditTextandroid:id="@+id/editTextId"android:layout_width="wrap_content"android:layout_height="wrap_content"style="@style/MyCustomeEditTextStyle" />
BUT if you are want it to be globally set once and set without the xml because you are generating your EditText programmatically like this:
EditText editTextFieldTitle = new EditText(this);
you can then set your style in the application style like this:
<style name="AppTheme" parent="@android:style/YourParentTheme"><item name="android:editTextStyle">@style/MyCustomeEditTextStyle</item></style>

editTextFieldTitle = new EditText(new ContextThemeWrapper(getBaseContext(),R.style.input_fields_single_line),null,0);

在EditText中有一个名为"styles"的属性，可以使用它。如果您想要自定义它，那么可以在drawable中创建自己的样式，创建一个新的XML文件，并通过使用styles属性将其链接到editText。
英文:
There is a attribute in EditText called styles use that.and if you want to customize it than make own style in drawable , A new XML and link to the editText using styles attribute.
