警告对话框 [英] Alert Dialog Box

问题描述

我在code一个警告对话框，我想一个值赋给一个变量作为取消按钮是pssed该对话框$ P $。

我的实际code为 -

 私人无效点击（）{
    AlertDialog.Builder建设者=新AlertDialog.Builder（Feedback.this）;
    builder.setTitle（反馈）;
    builder.setSingleChoiceItems（选项，-1，
            新DialogInterface.OnClickListener（）{

                公共无效的onClick（DialogInterface对话，诠释它）{
                    // TODO自动生成方法存根
                    切换（这）{
                    情况下0：
                        字符串URL =htt​​p://killmathsapp.blogspot.in/;
                        意图I =新的意图（Intent.ACTION_VIEW）;
                        i.setData（Uri.parse（URL））;
                        startActivity（ⅰ）;
                        打破;

                    情况1：
                        意图S =新意图（Intent.ACTION_SEND）;
                        s.setType（纯/文）;
                        s.putExtra（android.content.Intent.EXTRA_EMAIL，
                                新的String [] {[e-mail]}）;
                        s.putExtra（android.content.Intent.EXTRA_SUBJECT，
                                从应用反馈）;
                        startActivity（多个）;
                        打破;

                    }

                }
            }）;
    AlertDialog警报= builder.create（）;
    alert.setCancelable（真正的）;
    alert.show（）;
}
 

解决方案

很简单，在对话框中警报消息的方式...

 公共无效的onClick（视图v）
        {
            如果（somthing_wrong）
                          {
           对话D =新的对话框（AmitregistrationActivity.this）;
           d.setContentView（R.layout.detail）;
           d.setTitle（警告......）;
           d.show（）;
                  }
                其他{
                  要执行// code
                       }
             }
 

你也必须创建这样一个detail.xml文件

 ＆LT; ImageView的
    机器人：ID =@ + ID / imageView1
    机器人：layout_width =WRAP_CONTENT
    机器人：layout_height =WRAP_CONTENT
    机器人：layout_alignParentLeft =真
    机器人：layout_alignParentTop =真
    机器人：SRC =@可绘制/详细信息/＆GT;

＆LT;的TextView
    机器人：ID =@ + ID / textView1
    机器人：layout_width =WRAP_CONTENT
    机器人：layout_height =WRAP_CONTENT
    机器人：layout_alignParentTop =真
    机器人：layout_marginLeft =26dp
    机器人：layout_marginTop =15dp
    机器人：layout_toRightOf =@ + ID / imageView1
    机器人：文本=请填写所有的细节......机器人：TEXTSIZE =20dp/＆GT;
 

I have a alert dialog box in my code and I want to assign a value to a variable as the cancel button is pressed for that dialog.

My actual code is -

private void clicked() {
    AlertDialog.Builder builder = new AlertDialog.Builder(Feedback.this);
    builder.setTitle("FEEDBACK");
    builder.setSingleChoiceItems(options, -1,
            new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    switch (which) {
                    case 0:
                        String url = "http://killmathsapp.blogspot.in/";
                        Intent i = new Intent(Intent.ACTION_VIEW);
                        i.setData(Uri.parse(url));
                        startActivity(i);
                        break;

                    case 1:
                        Intent s = new Intent(Intent.ACTION_SEND);
                        s.setType("plain/text");
                        s.putExtra(android.content.Intent.EXTRA_EMAIL,
                                new String[] { "[e-mail]" });
                        s.putExtra(android.content.Intent.EXTRA_SUBJECT,
                                "feedback from app");
                        startActivity(s);
                        break;

                    }

                }
            });
    AlertDialog alert = builder.create();
    alert.setCancelable(true);
    alert.show();
}

解决方案

very simple way for alert message in dialog box...

       public void onClick(View v) 
        {
            if(somthing_wrong)
                          {
           Dialog d=new Dialog(AmitregistrationActivity.this);
           d.setContentView(R.layout.detail);
           d.setTitle("Warning....");
           d.show();
                  }
                else{
                  //Code that you want to execute 
                       }
             }

also you have to create an detail.xml file like this

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:src="@drawable/detail" />

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="26dp"
    android:layout_marginTop="15dp"
    android:layout_toRightOf="@+id/imageView1"
    android:text="Please fill all Details..." android:textSize="20dp"/>
