所以我试图制作一个穷人的交互式雷达图或蜘蛛图,我找不到。我确实发现了这个: Android Layout views rotated and spaced around a circle? 并且考虑在其中旋转搜索栏并且它有点起作用,但是搜索栏本身被某些边界截断/切断,我不知道它是什么。我尝试了一些填充的东西,但是他们没有帮助。
MainActivity代码如下所示:
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Context context = getApplicationContext();
final FrameLayout main = (FrameLayout)findViewById(R.id.main);
int numViews = 6;
for(int i = 0; i < numViews; i++)
{
// Create some quick TextViews that can be placed.
TextView v = new TextView(this);
SeekBar sb = new SeekBar(this);
// Set a text and center it in each view.
v.setText("View " + i);
v.setGravity(Gravity.CENTER);
v.setBackgroundColor(0xff00ffff);
// Force the views to a nice size (150x100 px) that fits my display.
// This should of course be done in a display size independent way.
FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(400, 75);
FrameLayout.LayoutParams lpv = new FrameLayout.LayoutParams(300, 75);
// Place all views in the center of the layout. We'll transform them
// away from there in the code below.
lp.gravity = Gravity.CENTER;
lpv.gravity = Gravity.CENTER;
lp.bottomMargin = 150;
lpv.bottomMargin = 150;
// Set layout params on view.
v.setLayoutParams(lpv);
sb.setLayoutParams(lp);
// Calculate the angle of the current view. Adjust by 90 degrees to
// get View 0 at the top. We need the angle in degrees and radians.
float angleDeg = i * 360.0f / numViews - 90.0f;
float angleRad = (float)(angleDeg * Math.PI / 180.0f);
// Calculate the position of the view, offset from center (300 px from
// center). Again, this should be done in a display size independent way.
v.setTranslationX(500 * (float)Math.cos(angleRad));
v.setTranslationY(500 * (float)Math.sin(angleRad));
sb.setTranslationX(250 * (float)Math.cos(angleRad));
sb.setTranslationY(250 * (float)Math.sin(angleRad));
// Set the rotation of the view.
v.setRotation(angleDeg +90f);
sb.setRotation(angleDeg );
main.addView(sb);
main.addView(v);
}
}
和activity_main.xml代码为:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Settings"
android:layout_marginBottom="150px"/>
</FrameLayout>
任何水平的搜索栏(如果有8个)或垂直看起来很好,但是那些对角线的搜索栏没有正确显示。结果如下:
所以视图1和2几乎没有显示条形图,尽管拇指都正确移动。视图4和5根本不显示。我应该改变什么才能使它们完全可见?非常感谢你!
编辑:添加numViews = 8和15
的屏幕截图奇怪的是,右侧只能看到一些对角线,左侧没有任何对角线。可能会有某种填充物#34;盒子&#34;还需要轮换吗?

它的Android设备问题不同的屏幕分辨率和密度。所以请阅读此内容 “支持多个屏幕”阅读本网站: https://developer.android.com/guide/practices/screens_support.html

我最近遇到了这个问题。但我正在使用Android Studio中的布局编辑器构建我的UI,并且想知道为什么旋转的搜索栏在预览中看起来很好。所以我尝试添加一个软件layerType
,这似乎有效!
android:layerType="software"
或者在你的情况下:
sb.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
希望这有帮助。

你还需要在manifest xml文件中支持不同的屏幕Open&#34; AndroidManifest&#34;并在android versionName之后添加以下内容。
<supports-screens android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:xlargeScreens="true"
android:anyDensity="true"
android:resizeable="true"/>
