问题描述

我试图创建一个SlidingDrawer与LinearLayout中含量超过的FrameLayout。

I'm trying to create a SlidingDrawer with LinearLayout content over a FrameLayout.

起初，这一切似乎罚款，我让我的SlidingDrawer的手柄在屏幕的底部。不过，如果我开始拖动手柄和内容开始显示，它就会通过手柄的边框矩形裁剪。如果我一路拖动手柄向上的全部内容最终被显示，但如果我现在拖动手柄向下，它将由内容的矩形边框被裁剪。此外，如果手柄是一路上涨，当我开始拖动它的全部内容消失。
我仍然可以点击那里的手柄应该是在屏幕上，拖动和内容将显示，但我需要猜出手柄。

At first it all seems fine, I get my SlidingDrawer's handle at the bottom of the screen.But then, if I start dragging the handle up and the content starts showing, it gets clipped by the border rectangle of the handle. If I drag the handle all the way up the entire content eventually gets shown, however if I now drag the handle down, it will be clipped by the border rectangle of the content. Also, if the handle is all the way up, as soon as I start dragging it the whole content disappears.
I can still click on where the handle should be on the screen, drag it and the content would show, but I need to guess where the handle is.

什么似乎导致，这是事实，我在短短SlidingDrawer之前的XML文件中的SurfaceView。
删除从XML的观点解决了这个问题，但我需要这个观点。

What seems to be causing this is the fact that I have a SurfaceView in the xml file just before SlidingDrawer.
Removing the view from the xml solves this problem, however I need this view.

这里的XML：

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <!--  Removing this DrawView from here solves the problem -->
    <com.package.DrawView
        android:id="@+id/main"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
    />

    <SlidingDrawer
        android:id="@+id/SlidingDrawer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:allowSingleTap="true"
        android:animateOnClick="true"
        android:handle="@+id/slideHandleButton"
        android:content="@+id/contentLayout"
        android:padding="10dip">

        <Button
            android:id="@+id/slideHandleButton"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/sliding_button">
        </Button>

        <LinearLayout
            android:id="@+id/contentLayout"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <Button
                android:id="@+id/clearButton"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Test">
            </Button>

        </LinearLayout>

    </SlidingDrawer>

</FrameLayout>

Java的：

Java:

package com.package;

import android.app.Activity;
import android.os.Bundle;

public class SlideTest extends Activity
{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);
    }
}

package com.package;

import android.content.Context;
import android.util.AttributeSet;
import android.view.SurfaceView;

public class DrawView extends SurfaceView
{
    public DrawView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
}

编辑：我刚刚注意到，如果drawView函数扩展视图，而不是SurfaceView这个问题消失。但是，我使用的是专用的绘图线程，并根据文件（和LunarLander例子）使用专用的绘图线程时，应制订一个SurfaceView。

I just noticed that if DrawView extends View and not SurfaceView this problem goes away.However, I'm using a dedicated drawing thread and according to the documentation (and LunarLander example) when using a dedicated drawing thread, it should draw to a SurfaceView.

任何帮助将是很大的AP preciated！

Any help would be greatly appreciated!
