カスタムコンポーネントの作成は初めてです。ProgressBarを拡張してカスタムプログレスバーを作成しています。しかし、この例外が発生します。

これを作成するための私のコードはここにあります..TextProgressBar.class
public class TextProgressBar extends ProgressBar {
Activity activity;
public TextProgressBar(Activity activity) {
super(activity);
this.activity = activity;
this.activity.setContentView(R.layout.custom_progress);
}
そして、Progress.javaアクティビティからこのクラスを呼び出しています
public class Progress extends Activity {
/** Called when the activity is first created. */
Button buttonClick;
TextProgressBar textProgressBar;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
buttonClick = (Button) findViewById(R.id.buttonClick);
buttonClick.setOnClickListener(new Click());
}
class Click implements OnClickListener
{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
textProgressBar = new TextProgressBar(Progress.this);
}
}
}
custom_progressのxmlはここにあります。
<?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="wrap_content"
android:orientation="vertical" >
<com.customprogress.TextProgressBar
android:id="@+id/progressBarWithText"
android:layout_width="100dp"
android:layout_height="100dp"
/>
</LinearLayout>
誰かがこれの解決策を知っているなら私を助けてください..事前に感謝します..
