您可以移动到所需的活动上按一下按钮。只需添加机器人：的onClick =的sendMessage此行

You can move to desired activity on button click. just add android:onClick="sendMessage"this line.

的xml：

 <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="sendMessage"
        android:text="@string/button" />

在您的主要活动只需添加这个方法：

In your main activity just add this method:

public void sendMessage(View view) 
{
    Intent intent = new Intent(FromActivity.this, ToActivity.class);
    startActivity(intent);
}

是啊不要忘记最重要的是要确定你的manifest.xml活动

Yeah and most important thing dont forget to define you activity in manifest.xml

 <activity
      android:name=".ToActivity"
      android:label="@string/app_name">          
 </activity>
