app第一次安装需要弹出同意服务协议和隐私政策，效果如下:

此处使用AlertDialog作为展示 布局

android:layout_width="match_parent"

android:layout_height="match_parent">

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginLeft="20dp"

android:layout_marginRight="20dp"

android:orientation="vertical"

android:background="@drawable/corner_shape_white"

android:padding="10dp">

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:id="@+id/btm1"

android:layout_gravity="center"

android:orientation="vertical">

android:layout_width="match_parent"

android:layout_height="50dp"

android:gravity="center"

android:text="服务协议和隐私政策"

android:textColor="@color/black"

android:textSize="18sp"/>

android:id="@+id/userArgTv"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:text="@string/user_arg_content"

android:textColor="@color/black"

android:textSize="15sp"/>

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginTop="30dp"

android:layout_height="45dp"

android:text="暂不同意"

android:textSize="17sp"

android:layout_marginRight="5dp"

android:textColor="@color/black"

style="?android:attr/borderlessButtonStyle"

android:background="@drawable/corner_bg_no_theme_selector"/>

android:id="@+id/agreeBtn"

android:layout_width="0dp"

android:layout_weight="1"

android:layout_height="45dp"

android:text="同意并接受"

android:textSize="17sp"

android:layout_marginLeft="5dp"

style="?android:attr/borderlessButtonStyle"

android:background="@drawable/corner_bg_theme_selector"

android:textColor="@color/black" />

public class ShowAgrementDialog extends AlertDialog {

private Context context;

private TextView agreeTv;

public static final int ARGEE_TEXT_CLICK = 1; //用户协议

public static final int SECRET_TEXT_CLICK = 2; //隐私协议

public static final int ARGEE_BTN_CLICK = 3; //同意按钮

public static final int NOT_ARGEE_BTN_CLICK = 4; //不同意按钮

private static int START_AG = 0; //用户协议需要加颜色的开始文字位置

private static int END_AG = 0;//结束

private static int START_SECRET = 0;//隐私开始文字位置

private static int END_SECRET = 0;//结束

private OnBtnClickListener listener;

public ShowAgrementDialog(Context context) {

super(context);

this.context = context;

}

public interface OnBtnClickListener {

void onClick(int type);

}

public void setOnBtnClickListener(OnBtnClickListener onBtnClickListener) {

this.listener = onBtnClickListener;

}

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.dialog_show_user_agreement);

initView();

}

private void initView() {

agreeTv = findViewById(R.id.userArgTv);

String argContent = context.getResources().getString(R.string.user_arg_content);

START_AG = argContent.indexOf("《服务协议》");

END_AG = START_AG + "《服务协议》".length();

START_SECRET = argContent.indexOf("《隐私政策》");

END_SECRET = START_SECRET + "《隐私政策》".length();

Log.d("测试起", START_AG + "");

Log.d("测试后", END_AG + "");

SpannableString spannableString = new SpannableString(argContent);

ForegroundColorSpan colorSpan = new ForegroundColorSpan(context.getResources().getColor(R.color.btntextcolor_blue));

ForegroundColorSpan colorSpan2 = new ForegroundColorSpan(context.getResources().getColor(R.color.btntextcolor_blue));

UnderlineSpan underlineSpan = new UnderlineSpan();

UnderlineSpan underlineSpan2 = new UnderlineSpan();

ClickableSpan userArgeeClick = new ClickableSpan() {//用户协议

@Override

public void onClick(@NonNull View view) {

Toast.makeText(context, "用户协议", Toast.LENGTH_SHORT).show();

}

@Override

public void updateDrawState(@NonNull TextPaint ds) {

ds.setUnderlineText(false);//去除连接下划线

ds.setColor(context.getResources().getColor(R.color.btntextcolor_blue));

ds.clearShadowLayer();

}

};

ClickableSpan secretClick = new ClickableSpan() {//隐私政策

@Override

public void onClick(@NonNull View view) {

Toast.makeText(context, "隐私政策", Toast.LENGTH_SHORT).show();

}

@Override

public void updateDrawState(@NonNull TextPaint ds) {

ds.setColor(context.getResources().getColor(R.color.btntextcolor_blue));

ds.setUnderlineText(false);//去除连接下划线

ds.clearShadowLayer();

}

};

findViewById(R.id.agreeBtn).setOnClickListener(view -> listener.onClick(ARGEE_BTN_CLICK));

findViewById(R.id.notAgreeBtn).setOnClickListener(view -> listener.onClick(NOT_ARGEE_BTN_CLICK));

spannableString.setSpan(colorSpan, START_AG, END_AG, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString.setSpan(underlineSpan, START_AG + 1, END_AG - 1, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString.setSpan(userArgeeClick, START_AG, END_AG, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString.setSpan(colorSpan2, START_SECRET, END_SECRET, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString.setSpan(underlineSpan2, START_SECRET + 1, END_SECRET - 1, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

spannableString.setSpan(secretClick, START_SECRET, END_SECRET, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

agreeTv.setMovementMethod(LinkMovementMethod.getInstance());

//设置点击背景色透明 解决点击时有阴影效果

agreeTv.setHighlightColor(context.getResources().getColor(android.R.color.transparent));

agreeTv.setText(spannableString);

setCanceledOnTouchOutside(false);

setCancelable(false);

}

}

最后在引导页调用

ShowAgrementDialog showAgrementDialog = new ShowAgrementDialog(this);

showAgrementDialog.show();

showAgrementDialog.setOnBtnClickListener(type -> {

switch (type) {

case ShowAgrementDialog.NOT_ARGEE_BTN_CLICK://不同意按钮

showAgrementDialog.dismiss();

finish();

break;

case ShowAgrementDialog.ARGEE_BTN_CLICK: //同意按钮

showAgrementDialog.dismiss();

requestPermission();

break;

}

});
