如何使用AlertDialog为绿色按钮和消息背景设置自定义样式。???
AlertDialog的定义：
AlertDialog.Builder alert = new AlertDialog.Builder(About.this, R.style.MY_AlertDialog);
和风格：
<style name="MY.AlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:windowBackground">@color/green</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowCloseOnTouchOutside">false</item>
</style>
您可以执行此操作，而无需使用自定义样式或像下面的代码那样夸大自定义视图。
public void createDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Do you want to exit from app");
builder.setCancelable(false);
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(ViewPagerStyle1Activity.this,
"You exit from app", Toast.LENGTH_LONG).show();
}
});
AlertDialog alert = builder.create();
alert.show();
TextView messageText = (TextView) alert
.findViewById(android.R.id.message);
messageText.setBackgroundColor(Color.RED);
Button nbutton = alert.getButton(DialogInterface.BUTTON_NEGATIVE);
nbutton.setBackgroundColor(Color.MAGENTA);
Button pbutton = alert.getButton(DialogInterface.BUTTON_POSITIVE);
pbutton.setBackgroundColor(Color.YELLOW);
}
