【问题描述】:
所以我正在尝试制作一个穷人的交互式雷达图或蜘蛛图,但我找不到。我确实找到了这个: Android Layout views rotated and spaced around a circle? 并考虑在其中旋转搜索栏,它有点工作,但搜索栏本身被一些边界剪裁/截断,我不知道它是什么。我尝试了一些使用填充的方法,但它们没有帮助。
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);
}
}
而activity_main.xml 代码是:
<?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(如果有 8 个)或垂直的搜索栏看起来都很好,但对角线的搜索栏显示不正确。结果是这样的:
所以视图 1 和 2 几乎不显示条形图,尽管拇指都正确移动。视图 4 和 5 根本不显示。我应该改变什么以使它们完全可见?非常感谢!
编辑:添加 numViews= 8 和 15 的屏幕截图
奇怪的是,右侧只有一些对角线可见,左侧什么都没有。是否也存在某种需要旋转的填充“框”?

我正在使用带有最新更新的 Nexus 5x... 7.1.2

您找到解决方案了吗?我也在寻找类似的东西。

不,我还没有找到解决方案,抱歉:/
