无法在android studio的列表中添加页脚

Question

我是Android编程的新手，如果之前有人问过这个问题，我很抱歉。 但是我无法在列表视图中添加页脚，其中包含来自服务的评论和评级数据。我只想要显示1个项目，之后应该显示更多的页脚。 我的代码是：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
        <rules>
      <rule name="HTTP to HTTPS redirect" stopProcessing="true">
        <match url="(.*)" />
      <conditions>
        <add input="{HTTPS}" pattern="off" ignoreCase="true" />
      </conditions>
      <action type="Redirect" redirectType="Found" url="https://{HTTP_HOST}/{R:1}" />
    </rule>
            <rule name="WordPress Rule" stopProcessing="true">
                <match url=".*" />
                <conditions>
                    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                </conditions>
                <action type="Rewrite" url="index.php" />
            </rule>
        </rules>
        </rewrite>
    </system.webServer>
</configuration>

但是这个页脚没有显示出来。这是我的logcat

// Footer to add
        final TextView tvReadAll = new TextView(this);
        tvReadAll.setTextSize(17f);
        tvReadAll.setGravity(Gravity.CENTER_HORIZONTAL);
        tvReadAll.setTextColor(R.drawable.list_selector);
        tvReadAll.setText("Read All Reviews");

        int limit =1;
        for(int length=0;length<limit;length++) {
            mLvReviews.getAdapter().getItem(1);
            mLvReviews.addFooterView(tvReadAll);
        }

        tvReadAll.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Utility.setListViewHeightBasedOnChildren(mLvReviews);
                tvReadAll.setVisibility(View.GONE);

            }
        });

        adapter = new UserReviewsAdapter(ProDetailedInfo.this, array);
        mLvReviews.setAdapter(adapter);
