我在更改警报对话框的复选框主题时遇到问题。我无法将选中的复选框颜色更改为我的 AccentColor。
这是我的样式代码
<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:checkboxStyle">@style/CustomCheckBox</item>
</style>
<style name="CustomCheckBox" parent="android:style/Widget.CompoundButton.CheckBox">
<item name="android:button">@drawable/activated_checkbox</item>
</style>
选择器:activated_checkbox
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- checked -->
<item android:state_checked="true" android:drawable="@color/AccentColor">
</item>
<item android:state_checked="false" android:drawable="@color/White">
</item>
</selector>
以及显示 AlertDialog 的方法。
private void showDialog() {
final CharSequence[] items = getResources().getStringArray(R.array.tipoDescargas);
final boolean[] states = {false, false, false};
AlertDialog.Builder builder = new AlertDialog.Builder(this,R.style.AlertDialogCustom);
builder.setTitle(getResources().getString(R.string.preguntaDescargas));
builder.setMultiChoiceItems(items, states, new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialogInterface, int item, boolean state) {
}
});
builder.setPositiveButton("Descargar", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
SparseBooleanArray CheCked = ((AlertDialog) dialog).getListView().getCheckedItemPositions();
if (CheCked.get(0) && CheCked.get(1) && CheCked.get(2))
Toast.makeText(getApplication(), "TODOS", Toast.LENGTH_SHORT).show();
if (CheCked.get(0)) {
Toast.makeText(getApplication(), "Item 1", Toast.LENGTH_SHORT).show();
}
if (CheCked.get(1)) {
Toast.makeText(getApplication(), "Item 2", Toast.LENGTH_SHORT).show();
}
if (CheCked.get(2)) {
Toast.makeText(getApplication(), "Item 3", Toast.LENGTH_SHORT).show();
}
}
});
builder.setNegativeButton("Cancelar", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});builder.create().show();
}
谁能帮帮我?谢谢

<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:checkedTextViewStyle">@style/CustomCheckBox</item>
</style>
<style name="CustomCheckBox" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:checkMark">@drawable/activated_checkbox</item>
</style>
解决方案
我找到了正确显示颜色的解决方案。
<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:listChoiceIndicatorMultiple">@drawable/activated_checkbox</item>
</style>
和选择器
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/checkedcheckbox24" android:state_checked="true"></item>
<item android:drawable="@drawable/uncheckedcheckbox24" android:state_checked="false"></item>
</selector>
最佳答案
使用这段代码,图标可以正确显示
<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:listChoiceIndicatorMultiple">@drawable/activated_checkbox</item>
</style>
和选择器代码
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/checkedcheckbox24" android:state_checked="true"></item>
<item android:drawable="@drawable/uncheckedcheckbox24" android:state_checked="false"></item>
</selector>
