我使用的是单一的选择中,我想,以取代默认的蓝色(标题行和单选按钮),我使用的标题栏中的橙色警报对话框。我可以使用 setCustomTitle()
,但我失去了试图摆脱这个该死的蓝更改为标题栏。
I'm using a single choice alert dialog in which I'd like to replace the default blue (the title line and the radio buttons) to the orange that I am using in the title bar. I was able to change to the title bar using setCustomTitle()
, but I am lost trying to get rid of this damn blue.
作为标题栏
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@color/orange" >
<TextView
android:id="@+id/alertTitle"
android:layout_width="match_parent"

android:textSize="18sp" />
</LinearLayout>
构建AlertDialog
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
View customTitle = View.inflate(MainActivity.this, R.layout.custom_alert_title, null);
builder.setCustomTitle(customTitle);
builder.setSingleChoiceItems(mAlertOptions, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// do stuff
dialog.dismiss();
}
}).create().show();
这是什么样子
我需要摆脱这个蓝色的!救命啊!

推荐答案
要更改标题分颜色的唯一方法就是使用 Resources.getIdentifier
联合 Window.findViewById
。该对号可以通过调用轻易改变 AlertDialog.Builder.setSingleChoiceItems(ListAdapter,INT,OnClickListener)
。
The only way to change the title divider color is to use Resources.getIdentifier
in combination with Window.findViewById
. The checkmark can be easily changed by calling AlertDialog.Builder.setSingleChoiceItems(ListAdapter, int, OnClickListener)
.
下面是一个例子:
单选项目布局
:我生成 your_radio_button
使用 Android的全息颜色
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:checkMark="@drawable/your_radio_button"
android:ellipsize="marquee"
android:gravity="center_vertical"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:paddingEnd="16dip"
android:paddingStart="16dip"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="?android:attr/textColorAlertDialogListItem" />
执行
final ListAdapter adapter = new ArrayAdapter<String>(this,
R.layout.select_dialog_singlechoice, android.R.id.text1, new String[] {
"Option 1", "Option 2"
});
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCustomTitle(getLayoutInflater().inflate(R.layout.custom_alert_title, null));
builder.setSingleChoiceItems(adapter, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// Do something
}
});
// Show the AlertDialog
final AlertDialog dialog = builder.show();
// Change the title divider
final Resources res = getResources();
final int titleDividerId = res.getIdentifier("titleDivider", "id", "android");
final View titleDivider = dialog.findViewById(titleDividerId);
titleDivider.setBackgroundColor(res.getColor(android.R.color.holo_orange_dark));
