为实现slidingdrawer另一种方式，现在已去，因为API 17 pcated $ P $ [英] Alternative way for implementing a slidingdrawer that has now been deprecated since api 17
问题描述
在我的应用程序我有一个滑动抽屉，在他们的图像按钮，并点击时，它显示图像的描述和信息。所以基本上我只使用一个XML文件，并为这一个Java文件中。 （不过，我注意到，增加更多的imagebuttons和法师来显示它需要一段时间来加载）。而现在，由于API 17日precating滑动抽屉让我有点担心为将来的下载应用程序的。现在的问题是，有没有实现这一点没有采用滑动抽屉或旋动一个替代方法。我真的不希望为每个图像XML和Java文件（我会拥有100 + XML的和java的） 这是我的code，我目前所面对的。
In my app I have a sliding drawer with image buttons in them and when clicked it displays the image description and info. So basically I am only using one XML file and one Java file for this. (But I have noticed that adding more imagebuttons and mages to display it takes a while to load). And now that since API 17 is deprecating the sliding drawer leaves me a bit worried for future downloads of the app. Now my question is, is there a alternative way to achieve this without using sliding drawer or spinner. I don't really want to create a xml and java file for each image (I'll end up with 100+ xml's and java's) Here is my code that I have at the moment.
XML：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/iM1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitStart"
android:adjustViewBounds="true"/>
</RelativeLayout>
</ScrollView>
<SlidingDrawer
android:id="@+id/sD1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:content="@+id/content"
android:handle="@+id/handle">
<Button
android:id="@+id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/icon_1" />
<RelativeLayout
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/icon_background1">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="@+id/asample"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/imageicon1"/>
.....
和Java的：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.campsites);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
final SlidingDrawer slider = (SlidingDrawer) findViewById(R.id.sD1);
final ImageView imageView = (ImageView) findViewById(R.id.iM1);
slider.animateOpen();
Button next = (Button) findViewById(R.id.asample);
Button next1 = (Button) findViewById(R.id.bsample);
..........
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
imageView.setImageDrawable(getResources().getDrawable(R.drawable.asample));
slider.animateClose();
}
});
next1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
imageView.setImageDrawable(getResources().getDrawable(R.drawable.bsample));
slider.animateClose();
}
});
............
任何人都可以请帮助或有做什么建议？
Can anyone please help or have a suggestion on what to do?
推荐答案
这是一个 SlidingDrawer 从左边，正确吗？如果是这样，你可以看看 DrawerLayout 。
This is a SlidingDrawer from the left, correct? If so, you can look into DrawerLayout.
这是Android的支持库的一部分，你应该能够用这个代替你的XML，而不是相当简单和向后兼容API4
This is part of the Android Support Library and you should be able to replace your XML with this instead fairly simply and be backwards compatible to API4
从该网页中，有一个例子
From that page, there is an example.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
从该网页的一些注意事项。
Some notes from that page
此布局展示了一些重要的布局特点：
This layout demonstrates some important layout characteristics:
- 的主要内容视图（上面的FrameLayout）必须是第一个孩子在DrawerLayout因为XML订单意味着Z排序和 抽屉必须对内容的顶部。主要内容视图设置 匹配父视图的宽度和高度，因为它重新presents的 当导航抽屉是隐藏整个UI。
- 的抽屉视图（ListView控件），必须指定其水平的重力与机器人：layout_gravity属性。为了支持从右到左 （RTL）的语言，指定为开始，而不是左的值（这样 抽屉出现时布局RTL右）。
- 在抽屉查看指定其宽度DP单位和高度父视图相匹配。抽屉宽度应不大于320dp更多 这样用户就可以随时看到主要内容的一部分。
- The main content view (the FrameLayout above) must be the first child in the DrawerLayout because the XML order implies z-ordering and the drawer must be on top of the content. The main content view is set to match the parent view's width and height, because it represents the entire UI when the navigation drawer is hidden.
- The drawer view (the ListView) must specify its horizontal gravity with the android:layout_gravity attribute. To support right-to-left (RTL) languages, specify the value with "start" instead of "left" (so the drawer appears on the right when the layout is RTL).
- The drawer view specifies its width in dp units and the height matches the parent view. The drawer width should be no more than 320dp so the user can always see a portion of the main content.
晴的区别在于， DrawerLayout 是顶级水平，你把你的XML在其中。因此，像这样（没有经过测试）：
Mostly the difference is that the DrawerLayout is top level and you put your XML within it. So something like this (totally untested):
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- your content surrounded by a layout to signify that it's actually content -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/iM1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitStart"
android:adjustViewBounds="true"/>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
<!-- your sliding menu in its own layout -->
<LinearLayout
android:layout_gravity="start"
android:layout_width="240dp"
android:layout_height="wrap_content">
<Button
android:id="@+id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/icon_1" />
<RelativeLayout
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/icon_background1">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="@+id/asample"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/imageicon1"/>
.....
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
