我在logcat中遇到了這個奇怪的錯誤，我嘗試了一些想到解決它並仍然得到它的東西。 這裏是logcat的：android.view.InflateException：二進制XML文件

，這是我的xml：
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:bitdraw="http://schemas.android.com/apk/res/com.dm.test" >
<view
class="com.dm.test.ui.BitCanvasActivity$CanvasView"
android:id="@+id/backgroundz"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<com.dm.test.widget.ActionButtons
android:id="@+id/btn_actions"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginBottom="135dp"
android:layout_gravity="bottom|center_horizontal" />
<com.dm.test.widget.ColorPicker
android:id="@+id/color_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center_horizontal"
android:orientation="horizontal"
bitdraw:colors="@array/color_picker_colors"
bitdraw:cols="3"
bitdraw:fils="5" />
</merge>
，並在的.java線55的這樣的：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bit_canvas); //line 55
mActionButtons = (ActionButtons) findViewById(R.id.btn_actions);
mColorPicker = (ColorPicker) findViewById(R.id.color_picker);
，這是內部的一部分等級：
public class CanvasView extends View {
public CanvasView(Context c) {
super(c);
}
public CanvasView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CanvasView (Context c, AttributeSet atr, int defstyle){
super(c, atr,defstyle);
}
@Override
protected void onDraw(Canvas canvas) { ... }
任何幫助將非常感激，因爲我認真地跑出了想法：S
您需要聲明內部類爲靜態。 看到這個[上計算器的答案] [1] [1]：http://stackoverflow.com/questions/4483433/error-inflating-inner-class-view –
