Android实现3D标签云效果

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：

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 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"}; 
   
  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); 
 } 
}
