最近业务需求，要求实现一个3D星球环绕效果，经过百般查找，终于找到了这个功能。

来先看看效果图：

首先还是添加第三方依赖库：

compile 'com.moxun:tagcloudlib:1.1.0'

布局：


<?xml version="1.0" encoding="utf-8"?> 
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 xmlns:app="http://schemas.android.com/apk/res-auto" 
 xmlns:tools="http://schemas.android.com/tools" 
 android:layout_width="match_parent" 
 android:layout_height="match_parent" 
 tools:context="com.example.administrator.my3d_demo.MainActivity"> 
 <com.moxun.tagcloudlib.view.TagCloudView 
  android:id="@+id/tag_cloud" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  android:layout_margin="10dp" 
  app:autoScrollMode="uniform" 
  app:darkColor="#ff00ff00" 
  app:lightColor="#ffff0000" 
  app:radiusPercent="0.5" 
  app:scrollSpeed="3" /> 
</android.support.constraint.ConstraintLayout>

MainActivity代码：


package com.example.administrator.my3d_demo; 
import android.graphics.Color; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import com.moxun.tagcloudlib.view.TagCloudView; 
public class MainActivity extends AppCompatActivity { 
 @Override 
 protected void onCreate(Bundle savedInstanceState) { 
  super.onCreate(savedInstanceState); 
  setContentView(R.layout.activity_main); 
  TagCloudView tagCloudView = (TagCloudView) findViewById(R.id.tag_cloud); 
  tagCloudView.setBackgroundColor(Color.LTGRAY); 
  TextTagsAdapter tagsAdapter = new TextTagsAdapter(new String[20]); 
  tagCloudView.setAdapter(tagsAdapter); 
 } 
}

一个适配器代码：


package com.example.administrator.my3d_demo; 
import android.content.Context; 
import android.support.annotation.NonNull; 
import android.util.Log; 
import android.view.Gravity; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.TextView; 
import com.moxun.tagcloudlib.view.TagsAdapter; 
import java.util.ArrayList; 
import java.util.Collections; 
import java.util.List; 
import java.util.Random; 
public class TextTagsAdapter extends TagsAdapter { 
 private List<String> dataSet = new ArrayList<>(); 
 public TextTagsAdapter(@NonNull String... data) { 
  dataSet.clear(); 
  Collections.addAll(dataSet, data); 
 } 
 @Override 
 public int getCount() { 
  return dataSet.size(); 
 } 
 @Override 
 public View getView(final Context context, final int position, ViewGroup parent) { 
  String[] name = {"1", "2", "3", "4", "5", "6", "7", "8", "9"}; 
  /*int[] name={R.mipmap.ic_launcher,R.mipmap.ic_launcher,R.mipmap.ic_launcher, 
    R.mipmap.ic_launcher,R.mipmap.ic_launcher,R.mipmap.ic_launcher, 
    R.mipmap.ic_launcher,R.mipmap.ic_launcher,R.mipmap.ic_launcher};*/ 
  Random rand = new Random(); 
  int randNum = rand.nextInt(9); 
  TextView tv = new TextView(context); 
  ViewGroup.MarginLayoutParams lp = new ViewGroup.MarginLayoutParams(100, 100); 
  tv.setLayoutParams(lp); 
  tv.setText("No." + name[randNum]); 
  tv.setGravity(Gravity.CENTER); 
  tv.setOnClickListener(new View.OnClickListener() { 
   @Override 
   public void onClick(View v) { 
    Log.e("Click", "Tag " + position + " clicked."); 
   } 
  }); 
  return tv; 
 } 
 @Override 
 public Object getItem(int position) { 
  return dataSet.get(position); 
 } 
 @Override 
 public int getPopularity(int position) { 
  return position % 7; 
 } 
 @Override 
 public void onThemeColorChanged(View view, int themeColor) { 
  ((TextView) view).setTextColor(themeColor); 
 } 
}
