我使用一个单一的选择警报对话框,在这个对话框中,我希望将默认的蓝色(标题行和单选按钮)替换为我在标题栏中使用的橙色。我能够用setCustomTitle()
换到标题栏,但是我无法摆脱这个该死的蓝色。
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:layout_height="match_parent"
android:padding="14dp"
android:gravity="center"
android:text="Alert Title"
android:textColor="@color/white"
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();
,这就是它看起来像
我要摆脱这蓝色!帮助!

改变标题分隔器颜色的唯一方法是结合使用Resources.getIdentifier
和Window.findViewById
。通过调用AlertDialog.Builder.setSingleChoiceItems(ListAdapter, int, OnClickListener)
,可以很容易地更改复选标记。
下面是一个例子:
单选择项布局:我使用Android Holo颜色。生成了your_radio_button
<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" />
Implementation
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));
