我正在尝试使用2个NumberPickers创建一个对话框。我希望它们是默认的Holo主题风格。我找不到任何好的例子。到目前为止,我得到了:
LayoutInflater inflater = (LayoutInflater)
getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View npView = inflater.inflate(R.layout.number_picker_dialog, null);
NumberPicker minPicker = (NumberPicker) npView.findViewById(R.id.min_picker);
minPicker.setMaxValue(100);
minPicker.setMinValue(0);
NumberPicker maxPicker = (NumberPicker) npView.findViewById(R.id.max_picker);
maxPicker.setMaxValue(100);
maxPicker.setMinValue(0);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Text Size:");
builder.setView(npView);
builder.setPositiveButton("Okay",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
builder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
dialog = builder.create();
dialog.show();
number_picker_dialog xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:holo="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:gravity="center">
<NumberPicker
android:id="@+id/min_picker"
android:width="100dip"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:/>
<NumberPicker
android:id="@+id/max_picker"
android:width="100dip"
android:layout_height="wrap_content"
android:layout_width="wrap_content"/>
</LinearLayout>
但是colorpicker文本是白色的(就像背景一样),我不能设置NumberPicker的textColor。
如何设置textColor或者有人知道一个好的NumberPicker示例吗?

我发现问题为什么我的NumberPicker不是Holo.Light样式:
而不是打电话:
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View npView = inflater.inflate(R.layout.number_picker_dialog, null);
我通过致电解决了这个问题:
View npView = getLayoutInflater().inflate(R.layout.number_picker_dialog, null);

我的方法是创建一个Custom Dialog类,如下所示。
public class CustomDialog extends Dialog {
public CustomDialog(Context context) {
super(context, R.style.customDialog); //use your style id from styles.xml
}
public void setNumberDialog() {
setContentView(R.layout.number_picker_dialog);
//add required listeners
show();
}
}
从调用acitivty调用对话框。
new CustomDialog(context).setNumberDialog();
样式参数在styles.xml中定义
<style name="customDialog" parent="android:Theme.Dialog">
<item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
<item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
<item name="android:background">@android:color/transparent</item>
<item name="android:textColor">@color/textColorWhite</item>
</style>

尝试:
<NumberPicker
style="@android:style/TextAppearance">
</NumberPicker>
