當螢幕旋轉時我什麼都不想做

    @Override

    public void onConfigurationChanged(Configuration newConfig) {

      super.onConfigurationChanged(newConfig);

    }

    <activity

            ...

            ...

            android:configChanges="orientation|keyboardHidden|screenSize"        

    ...>

監控我的back鍵盤

@Override

public void onBackPressed() {

        if (想要真地執行back的時候）

                super.onBackPressed();

        else

                do something...

}

取得parent的size

tv_title.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

將捲軸轉到最底

scrollView.post(new Runnable() {   //捲軸元件scrollView

@Override    

public void run() {           

scrollView.fullScroll(View.FOCUS_DOWN);                  

}

});

TextView 跑馬燈效果

自己實驗過ok：

title.setSingleLine();

title.setEllipsize(TextUtils.TruncateAt.valueOf("MARQUEE"));

title.setMarqueeRepeatLimit(100);

title.setFocusable(true);

title.setSelected(true);

網路上找到的資料：

Marquee - TextView的跑馬燈效果

在layout加入以下屬性：

↓即使字串長度超過TextView的寬,也以單行顯示(超過的就算了)

android:singleLine="true"

↓設置跑馬燈功能

android:ellipsize="marquee"

↓跑馬燈次數無限制

android:marqueeRepeatLimit="marquee_forever"

最後必須取得焦點才能看到跑馬燈動起來~有兩種方式：
一、在layout加入屬性
         android:focusableInTouchMode="true"
         android:focusable="true"

main.xml

01.< TextView

02.android:layout_width="fill_parent"

03.android:layout_height="wrap_content"

04.android:text="Marquee - TextView的跑馬燈效果"

05./>

06.< TextView

07.android:id="@+id/tv_marquee"

08.android:layout_width="fill_parent"

09.android:layout_height="wrap_content"

10.android:text="Marquee - TextView的跑馬燈效果"

11.android:textSize="30sp"

12.android:textColor="@color/deeppink"

13.android:singleLine="true"

14.android:ellipsize="marquee"

15.android:marqueeRepeatLimit="marquee_forever"

16.android:focusableInTouchMode="true"

17.android:focusable="true"

18./>

二、修改src, 加上setSelected(true)

Marquee_TextView.java

01.public class Marquee_TextView extends Activity

02.{

03.TextView tv_marquee;

04./** Called when the activity is first created. */

05.@Override

06.public void onCreate(Bundle savedInstanceState)

07.{

08.super.onCreate(savedInstanceState);

09.setContentView(R.layout.main);

10. 

11.tv_marquee = (TextView) findViewById(R.id.tv_marquee);    

12. 

13.tv_marquee.setSelected(true);

14.}
