2.点击用户使用协议或隐私政策时，显示dialog弹窗

String str = initAssets("yszc.txt");
final View inflate = LayoutInflater.from(mActivity).inflate(R.layout.dialog_xieyi_yinsi_style, null);
TextView tv_title = (TextView) inflate.findViewById(R.id.tv_title);
tv_title.setText("隐私政策");
TextView tv_content = (TextView) inflate.findViewById(R.id.tv_content);
tv_content.setText(str);
final Dialog dialog = new AlertDialog
        .Builder(mActivity)
        .setView(inflate)
        .show();
final WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
params.width = 800;
params.height = 1200;

 */
public String initAssets(String fileName) {
    String str = null;
    try {
        InputStream inputStream = getAssets().open(fileName);

        str = getString(inputStream);
    } catch (IOException e1) {
        e1.printStackTrace();
    }
    return str;
}
public static String getString(InputStream inputStream) {
    InputStreamReader inputStreamReader = null;
    try {
        inputStreamReader = new InputStreamReader(inputStream, "UTF-8");
    } catch (UnsupportedEncodingException e1) {
        e1.printStackTrace();
    }
    BufferedReader reader = new BufferedReader(inputStreamReader);
    StringBuffer sb = new StringBuffer("");
    String line;
    try {
        while ((line = reader.readLine()) != null) {
            sb.append(line);
            sb.append("\n");
        }
    } catch (IOException e) {
