开发时候需要对整个APP风格统一,所以对话框这种都是需要统一样式的,这种就需要自定义对话框了,可以自定义设置左右按钮文字,标题、内容提示、标题下面还有图标
效果图:
代码使用:
CommonDialog dialog = new CommonDialog(getActivity());
dialog.setMessage(message)
.setTitle("提示")
.setSingle(false)
.setNegtive("取消")
.setPositive("确定").setOnClickBottomListener(new CommonDialog.OnClickBottomListener() {
@Override
public void onPositiveClick() {
dialog.dismiss();
//确定操作
}
@Override
public void onNegtiveClick() {
dialog.dismiss();
//取消操作
}
}).show();
