我有这个简单的布局：

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

android:id="@+id/surfaceView1"

android:layout_width="fill_parent"

android:layout_height="0dp"

android:layout_weight = "1" />

android:id="@+id/linearLayout1"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:gravity="center" >

android:id="@+id/button1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="button1" />

android:id="@+id/button2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="button2" />

这符合并且应用运行完美.

我想用我自己的自定义SurfaceView替换通用的SurfaceView：

import android.content.Context;

import android.view.SurfaceHolder;

import android.view.SurfaceView;

public class PuzzleView extends SurfaceView implements SurfaceHolder.Callback {

public PuzzleView(Context context) {

super(context);

// TODO Auto-generated constructor stub

}

@Override

public void surfaceChanged(SurfaceHolder holder, int format, int width,

int height) {

// TODO Auto-generated method stub

}

@Override

public void surfaceCreated(SurfaceHolder holder) {

// TODO Auto-generated method stub

}

@Override

public void surfaceDestroyed(SurfaceHolder holder) {

// TODO Auto-generated method stub

}

}

并在布局中使用xml：

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

android:id="@+id/surfaceView1"

android:layout_width="fill_parent"

android:layout_height="0dp"

android:layout_weight = "1" />

.

.

.

一旦活动创建,我得到一个例外：

public class MyActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.game);

}

10-29 19:56:25.921: E/AndroidRuntime(287): java.lang.RuntimeException: Unable to start activity ComponentInfo{ybz.pack1/ybz.pack1.MyActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class PuzzleView

这是不允许的我找不到任何这样做的例子.

编辑：

除了下面给出的解决方案,还需要将所有的SurfaceView构造函数添加到PuzzleView中：

public PuzzleView(Context context, AttributeSet attrs, int defStyle) {

super(context, attrs, defStyle);

// TODO Auto-generated constructor stub

}

public PuzzleView(Context context, AttributeSet attrs) {

super(context, attrs);

// TODO Auto-generated constructor stub

}
