我一直在无缘无故地挣扎,我不明白为什么。这是我的java代码:
public class SousRubrique extends RelativeLayout {
private View sousRubriqueView;
private TextView titleTextView;
public SousRubrique(Context context, AttributeSet attrs, int defStyle) {
super(context);
init(context);
}
public SousRubrique(Context context, AttributeSet attrs) {
super(context);
init(context);
}
public SousRubrique(Context context) {
super(context);
init(context);
}
// Initialization methods
public void init(Context context){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
setSousRubriqueView(inflater.inflate(R.layout.sousrubrique, this));
bind();
}
public void bind(){
setTitleTextView((TextView) sousRubriqueView.findViewById(R.id.sousRubriqueTitle));
}
// end
public void setTitle(String title){
titleTextView.setText(title);
}
public TextView getTitleTextView() {
return titleTextView;
}
public void setTitleTextView(TextView titleTextView) {
this.titleTextView = titleTextView;
}
public View getSousRubriqueView() {
return sousRubriqueView;
}
public void setSousRubriqueView(View sousRubriqueView) {
this.sousRubriqueView = sousRubriqueView;
}
}
这是我的 xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/red"
android:orientation="vertical" >
<TextView
android:id="@+id/sousRubriqueTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Sous-Rubrique"
android:layout_centerInParent="true"
android:textColor="@android:color/white" />
为什么 Eclipse 告诉我 bind 方法存在 java 空指针问题?
