我一直試圖設置一個TextSwitcher加載從XML文件的TextView。我有一個使用一個空的TextView確定工作這一基本TextSwitcher例如:從XML加載TextView到TextSwitcher
.java
public class TextSwitcherTest extends Activity
{
private TextSwitcher textSwitcher;
private ViewFactory viewFactory = new ViewFactory()
{
public View makeView()
{
TextView textView = new TextView(TextSwitcherTest.this);
return textView;
}
};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textSwitcher = (TextSwitcher) findViewById(R.id.textSwitcher);
textSwitcher.setFactory(viewFactory);
Animation in = AnimationUtils.loadAnimation(this,android.R.anim.fade_in);
Animation out = AnimationUtils.loadAnimation(this,android.R.anim.fade_out);
textSwitcher.setInAnimation(in);
textSwitcher.setOutAnimation(out);
textSwitcher.setText("test ok");
}
}
-
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextSwitcher
android:id="@+id/textSwitcher"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
但是,當我改變代碼,試圖從一個XML文件加載一個TextView,它吐出一堆錯誤。下面是修改後的代碼:
.java
public class TextSwitcherTest extends Activity
{
private TextSwitcher textSwitcher;
private ViewFactory viewFactory = new ViewFactory()
{
public View makeView()
{
LayoutInflater inflater = LayoutInflater.from(TextSwitcherTest.this);
TextView textView = (TextView) inflater.inflate(R.id.textView,null);
return textView;
}
};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textSwitcher = (TextSwitcher) findViewById(R.id.textSwitcher);
textSwitcher.setFactory(viewFactory);
Animation in = AnimationUtils.loadAnimation(this,android.R.anim.fade_in);
Animation out = AnimationUtils.loadAnimation(this,android.R.anim.fade_out);
textSwitcher.setInAnimation(in);
textSwitcher.setOutAnimation(out);
textSwitcher.setText("test ok");
}
}
-
textview.xml
<?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" >
<TextView
android:id="@+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
</LinearLayout>
任何人都可以給您一個建議,我要去哪裏錯了嗎?代碼編譯好,但我確定這是與LayoutInflater被濫用在某種方式?

好吧,對不起,我沒有包括他們更早! – Spoonface 2012-07-22 03:58:27
