RadioButtonGroup没有显示出来

在你解决按钮成功后，你们现在我有一个问题，无线电通讯组没有出现

这是代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:android2="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

<LinearLayout
    android:id="@+id/linearLayout1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:weightSum="10" >

    <TextView
        android:id="@+id/secondLine"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" 
        android:text="@string/Greetings" />

    <Button
        android:id="@+id/Button1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="HelloWord" />
</LinearLayout>

<LinearLayout
    android:id="@+id/linearLayout2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:orientation="horizontal"
    android:weightSum="10"
    android2:baselineAligned="_baseline" >

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="3.3"
        android:background="#ff0000"
        android:gravity="center"
        android:text="red"
        android:textColor="#000000" />

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="3.4"
        android:gravity="center"
        android:background="#00ff00"
        android:text="green"
        android:textColor="#000000"

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="3.3"
        android:gravity="center"
        android:background="#0000ff"
        android:text="blue"
        android:textColor="#000000" 

</LinearLayout>

<RadioGroup
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/myRadioGroup"
    android:orientation="horizontal">

<RadioButton
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weight="1"
    android:id="@+id/myRadioButtonRed" />

 <RadioButton
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weight="1"
    android:id="@+id/myRadioButtonGreen" />

  <RadioButton
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weight="1"
    android:id="@+id/myRadioButtonBlue" />

     </LinearLayout>
      </LinearLayout>

注意：即时通讯有一个错误说这个TextView android：layout_width =“fill_parent”android：layout_weight =“fill_parent”android：layout_weight =“3.3”android：gravity =“center”android：background =“＃0000ff”android：text =“蓝色“android：textColor =”＃000000“后面必须跟一个属性说明，我希望我能得到帮助和感谢

它应该是这样的

button1.setOnClickListener(new OnClickListener()
{
  public void onClick(View v)
  {
     //stuff
  }
});

button2.setOnClickListener(new OnClickListener()
{
  public void onClick(View v)
  {
     // stuff
  }
});

Button.OnClickListener myListener = new Button.OnClickListener()

View.OnClickListener myListener = new View.OnClickListener()

只需使用这种方式

            @Override
            public void onCreate(Bundle savedInstanceState) 
            {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);

                Button Button1=(Button)findViewById(R.id.Button1);
                Button1.setOnClickListener(mClickListener);
            }

            View.OnClickListener mClickListener =new OnClickListener()
            {           
                @Override
                public void onClick(View v) {
                // write your code here

                }
            };
