Android 用のカスタム コントロールをコーディングしていますが、次の問題と混同しています。View.inflate()
静的メソッドを呼び出そうとすると (次のコードを参照)、実行時例外が発生しますandroid.view.InflateException
。私の見解のためのコードがあります
public class NavigationView extends RelativeLayout implements NewRadioConst {
private TextView centerLabel;
private Context context;
private Typeface font;
private ImageView leftArrow;
private TextView leftLabel;
private View leftWrapper;
private ImageView rightArrow;
private TextView rightLabel;
private View rightWrapper;
public NavigationView(Context paramContext)
{
this(paramContext, null);
}
public NavigationView(Context paramContext, AttributeSet paramAttributeSet)
{
this(paramContext, paramAttributeSet, 0);
}
public NavigationView(Context paramContext, AttributeSet paramAttributeSet, int paramInt)
{
super(paramContext, paramAttributeSet, paramInt);
this.context = paramContext;
View.inflate(context, R.id.navView1, this); //this line take the exception
}
}
そして、ここに私が膨らませようとするxmlがあります
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/navView1" >
<FrameLayout android:id="@+id/centerWrapper" android:layout_centerInParent="true" style="@style/WrapContent">
<ImageView android:layout_gravity="center" android:id="@+id/centerBg" android:layout_width="90.0dip" android:layout_height="30.0dip" android:src="@drawable/center_bg" />
<TextView android:layout_gravity="center" android:id="@+id/centerLabel" android:text="@string/music" style="@style/TextLabel" />
</FrameLayout>
<LinearLayout android:id="@+id/leftWrapper" android:clickable="true" android:layout_centerVertical="true" style="@style/WrapContent">
<TextView android:textSize="12.0dip" android:layout_gravity="center_vertical" android:id="@+id/leftLabel" android:layout_marginLeft="8.0dip" android:text="@string/info" android:singleLine="true" style="@style/TextLabel" />
<ImageView android:layout_gravity="center_vertical" android:id="@+id/leftArrow" android:layout_width="50.0dip" android:layout_height="30.0dip" android:src="@drawable/left_arrow" />
</LinearLayout>
<LinearLayout android:id="@+id/rightWrapper" android:clickable="true" android:layout_centerVertical="true" style="@style/WrapContent">
<ImageView android:layout_gravity="center_vertical" android:id="@+id/rightArrow" android:layout_width="50.0dip" android:layout_height="30.0dip" android:src="@drawable/right_arrow" />
<TextView android:textSize="12.0dip" android:layout_gravity="center_vertical" android:id="@+id/rightLabel" android:layout_marginRight="8.0dip" android:text="@string/news" android:singleLine="true" style="@style/TextLabel" />
</LinearLayout>
</RelativeLayout>
ここにlogcatがあります
