机器人，动画，如何进出的屏幕布局滑动？ [英] Android, animation, How to sliding in and out a layout from screen?

问题描述

在我的应用程序需要通过相机来记录。在拍摄过程中我展示了一些项目，如在屏幕菜单上。我要当用户点击一个箭头滑出菜单，屏幕，它在当用户触摸屏幕上滑动。

In my application I need to record by camera. During recording I show some items as menu on screen. I need to slide out menu from screen when user clicks an arrow and slide it in when user touched the screen.

我有两个问题。 1），看来我的动画不能正常工作。 2）当我设置RelativeLayout的，以显示/隐藏只是认为生效，摄像头视图不得到整个画面，你在图片看到（我不希望看到黑色背景）。

I have two problem. 1) It seems my animation doesn't work. 2) when i set RelativeLayout to visible/invisible just the view take effect, camera view doesn't get the whole of screen as you see in images (I don't want see black background).

R.anim.slide_in_up：

R.anim.slide_in_up:

<?xml version="1.0" encoding="utf-8"?>

<translate 
    xmlns:android       = "http://schemas.android.com/apk/res/android"
    android:fromYDelta  = "100%p" 
    android:toYDelta    = "0%p"
    android:duration    = "3000" />

R.anim.slide_out_up：

R.anim.slide_out_up:

<?xml version="1.0" encoding="utf-8"?>

<translate 
    xmlns:android       = "http://schemas.android.com/apk/res/android"
    android:fromYDelta  = "0%p" 
    android:toYDelta    = "100%p"
    android:duration    = "3000" />

code，用于显示slide_in_up：

Code, for showing slide_in_up:

rlMenu = (RelativeLayout) findViewById(R.id.rlMenu);
        imHide  = (ImageView) findViewById(R.id.btn_hide);
        imHide.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                rlMenu.setVisibility(View.INVISIBLE);
                overridePendingTransition(R.anim.slide_in_up, R.anim.slide_out_up);
            }
        });

code，用于显示slide_out_up：

Code, for showing slide_out_up:

@Override
    public boolean onTouchEvent(MotionEvent event) {

        rlMenu.setVisibility(View.VISIBLE);
        overridePendingTransition(R.anim.slide_out_up, R.anim.slide_in_up);

        return super.onTouchEvent(event);
    }

屏幕布局：

<?xml version="1.0" encoding="utf-8"?>

     </RelativeLayout>
</LinearLayout>

推荐答案

答到的第二个问题。试着改变如下布局：

Answer to second question. Try changing your layout as below:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <FrameLayout
        android:id="@+id/camera_preview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

    <RelativeLayout
        android:id="@+id/rlMenu"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:orientation="horizontal" >

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:orientation="horizontal" >

            <ImageView
                android:id="@+id/btn_hide"
                android:layout_width="40dip"
                android:layout_height="wrap_content"
                android:layout_marginBottom="10dip"
                android:layout_marginTop="10dip"
                android:contentDescription="@string/menu_contentdescription"
                android:scaleType="fitXY"
                android:src="@drawable/btn_record_hide" />

            <ImageView
                android:id="@+id/btn_record"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="10dip"
                android:layout_toRightOf="@id/btn_hide"
                android:contentDescription="@string/menu_contentdescription"
                android:src="@drawable/btn_record_start" />

            <ImageView
                android:id="@+id/btn_stop"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginBottom="10dip"
                android:layout_marginTop="10dip"
                android:layout_toRightOf="@id/btn_record"
                android:clickable="false"
                android:contentDescription="@string/menu_contentdescription"
                android:src="@drawable/btn_record_stop" />
        </LinearLayout>

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:orientation="horizontal" >

            <Button
                android:id="@+id/btn_done"
                style="@style/simpletopic.bold"
                android:layout_width="wrap_content"
                android:layout_height="50dip"
                android:layout_alignParentRight="true"
                android:background="@drawable/btn_record_done"
                android:paddingLeft="15dip"
                android:text="@string/Record_btn" />
        </LinearLayout>
    </RelativeLayout>

</RelativeLayout>

我也有类似的情况与傩俗图形页面。

I had a similar situations with a custum MapView.
