解决方案
您在设置不正确的听众。为了使听众工作，你必须点击的ListView 排一次，以实际设置的侦听器按钮和的TextView 。正确的方法是设置听众在 getView 方法，当你布局的意见。
先删除code你在 onListItemClick 回调有，然后修改适配器。我已经重写你的适配器，更高效的版本（虽然越来越多的可以改进）。由于code是大，你可以在这里找到新的适配器 https://gist.github.com/3463215 。看看这是你想要的。

i have a listactivity app , each row cotain TEXT and BUTTON , both text and button must be clickable (what im try to get it ) , when click the text it will open MyDay activity and when click button it will open My_videos activity .
whats happen exactly when you open the app and click on any button , it do no click action in any button in all rows , but when you click any row text so it will open MyDay activity then click any button in the first row ONLY , it will open My_videos activity which is videoview , but in the same time the other buttons is not clickable in the rest of rows .
any advice will be appreciated ,
THANKS.

解决方案
You are setting the listeners incorrect. In order for the listeners to work you would have to click the ListView row once to actually set the listeners for the Buttons and TextView. The correct way would be to set the listeners in the getView method when you layout the views.
First delete the code you have in the onListItemClick callback and then modify the adapter. I've rewritten your adapter to a more efficient version(although more improvements could be made). As the code is big you can find the new adapter here https://gist.github.com/3463215 . See if this is what you want.
The R.layout.video layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="One" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Two" />
<Button
android:id="@+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="three" />
<Button
android:id="@+id/button4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Four" />
<Button
android:id="@+id/button5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Five" />
</LinearLayout>
<VideoView
android:id="@+id/videoView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
