Use visibility action with layouts 对布局使用可见性操作

For Example 例如 

        LinearLayout lly1 = (LinearLayout)findViewById(R.id.lly1);
        LinearLayout lly2 = (LinearLayout)findViewById(R.id.lly1);
        LinearLayout lly3 = (LinearLayout)findViewById(R.id.lly1);
        LinearLayout lly4 = (LinearLayout)findViewById(R.id.lly1);


  public void onClick(View v) {

switch(v.getId()){

case R.id.categoriaA1:

    // add layer a1
   lly1.setVisibility(v.VISIBLE);
   lly2.setVisibility(v.GONE);
   lly3.setVisibility(v.GONE);
   lly4.setVisibility(v.GONE);
    break;

case R.id.categoriaA2:
    // add layer a2
   lly2.setVisibility(v.VISIBLE);
   lly1.setVisibility(v.GONE);
   lly3.setVisibility(v.GONE);
   lly4.setVisibility(v.GONE);
    break;
case R.id.categoriaA3:
    //add  layer A3
   lly3.setVisibility(v.VISIBLE);
   lly2.setVisibility(v.GONE);
   lly1.setVisibility(v.GONE);
   lly4.setVisibility(v.GONE);
    break;
case R.id.categoriaA4:
    // add layer A4
   lly4.setVisibility(v.VISIBLE);
   lly2.setVisibility(v.GONE);
   lly3.setVisibility(v.GONE);
   lly1.setVisibility(v.GONE);

    break;

} }

Where coming to layout activity_main.xml 去哪里布局activity_main.xml 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <LinearLayout
        android:id="@+id/lly1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:visibility="visible" >
    </LinearLayout>

    <LinearLayout
        android:id="@+id/lly2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:visibility="gone" >
    </LinearLayout>

    <LinearLayout
        android:id="@+id/lly3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:visibility="gone" >
    </LinearLayout>

    <LinearLayout
        android:id="@+id/lly4"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:visibility="gone" >
    </LinearLayout>

</RelativeLayout>

You can change source or background of your target imageView when clicked. 单击时可以更改目标imageView的源或背景。
For example 例如 

ImageView imageview = (ImageView) root.findViewById(R.id.categoriaA1);
imageview.setBackground(Drawable your_background);

and in JAVA code do this against the button click: 并在Java代码中针对按钮单击执行此操作： 

 LinearLayout anteprimaAvatarLinear= (LinearLayout)findViewById(R.id.anteprimaAvatarLinear);
 ImageView anteprimaAvatar= (ImageView) findViewById(R.id.anteprimaAvatar);
 anteprimaAvatarLinear.setVisibility(v.VISIBLE); 
 anteprimaAvatar..setVisibility(v.GONE);  // OR INVISIBLE
