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"}; 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); } }
