Anrdroid使用SpannableStringBuilder实现隐私政策和服务协议

背景

本人所在公司的APP被CNAAC(国家移动互联网应用安全管理中心)通报APP没有隐私政策功能而被下架，记录解决该问题的方法。在Android中，TextView 可以通过SpannableStringBuilder设置富文本，并且在文本中可以设置点击事件，以下是实现代码：

import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.text.Spannable;import android.text.SpannableStringBuilder;import android.text.method.LinkMovementMethod;import android.text.style.ClickableSpan;import android.view.View;import android.widget.Button;import android.widget.CheckBox;import android.widget.TextView;import android.widget.Toast;public class MainActivity extends AppCompatActivity implements View.OnClickListener {    private Button btnLogin;    private CheckBox checkBox;    private TextView tvPrivacy;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initView();        initData();    }    private void initView() {        btnLogin=findViewById(R.id.btn_login);        checkBox=findViewById(R.id.checkBox);        tvPrivacy=findViewById(R.id.tv_privacy);        btnLogin.setOnClickListener(this);    }    private void initData() {//        我同意本DEMO的隐私政策和服务协议        SpannableStringBuilder builder=new SpannableStringBuilder(getString(R.string.string_privacy));        ClickableSpan clickSpanPrivacy=new ClickableSpan() {            @Override            public void onClick( View widget) {//                跳转隐私政策网址                Toast.makeText(MainActivity.this, getString(R.string.string_toast_to_privacy), Toast.LENGTH_SHORT).show();            }        };        builder.setSpan(clickSpanPrivacy,9,13, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);        ClickableSpan clickableSpanProtocol=new ClickableSpan() {            @Override            public void onClick( View widget) {//                跳转服务协议                Toast.makeText(MainActivity.this, getString(R.string.string_toast_to_service), Toast.LENGTH_SHORT).show();            }        };        builder.setSpan(clickableSpanProtocol,14,18,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);        tvPrivacy.setText(builder);        tvPrivacy.setMovementMethod(LinkMovementMethod.getInstance());//调用此方法时文字点击事件才有效    }    @Override    public void onClick(View v) {        if(!checkBox.isChecked()){//            请同意隐私政策和服务协议            Toast.makeText(this, getString(R.string.string_toast_privacy_service), Toast.LENGTH_SHORT).show();        }else {            Toast.makeText(this, getString(R.string.string_toast_login_success), Toast.LENGTH_SHORT).show();        }    }}
