AlertDialog.png
使用方法 example:
DialogUtil.showAlertDialog(getActivity(), R.mipmap.restart, "退出提示", "你确定要退出吗？"),
"确定", "取消", true, new DialogUtil.AlertDialogBtnClickListener() {
@Override
public void clickPositive() {
//positive
}
@Override
public void clickNegative() {
//negative
}
});
工具类主要代码
public class DialogUtil {
private static AlertDialog dialog;
/**
* @param activity Context
* @param iconRes 提示图标
* @param title 提示标题
* @param msg 提示内容
* @param positiveText 确认
* @param negativeText 取消
* @param cancelableTouchOut 点击外部是否隐藏提示框
* @param alertDialogBtnClickListener 点击监听
*/
public static void showAlertDialog(Activity activity, int iconRes, String title, String msg,
String positiveText, String negativeText, boolean
cancelableTouchOut, final AlertDialogBtnClickListener
alertDialogBtnClickListener) {
View view = LayoutInflater.from(activity).inflate(R.layout.custom_dialog_layout, null);
ImageView mIcon = view.findViewById(R.id.icon);
TextView mTitle = view.findViewById(R.id.title);
TextView mMessage = view.findViewById(R.id.message);
Button positiveButton = view.findViewById(R.id.positiveButton);
Button negativeButton = view.findViewById(R.id.negativeButton);
mIcon.setImageResource(iconRes);
mTitle.setText(title);
mMessage.setText(msg);
positiveButton.setText(positiveText);
negativeButton.setText(negativeText);
positiveButton.setOnClickListener(v -> {
alertDialogBtnClickListener.clickPositive();
dialog.dismiss();
});
negativeButton.setOnClickListener(v -> {
alertDialogBtnClickListener.clickNegative();
dialog.dismiss();
});
AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setView(view);
builder.setCancelable(true); //返回键dismiss
//创建对话框
dialog = builder.create();
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);//去掉圆角背景背后的棱角
dialog.setCanceledOnTouchOutside(cancelableTouchOut); //失去焦点dismiss
dialog.show();
}
public interface AlertDialogBtnClickListener {
void clickPositive();
void clickNegative();
}
}
