有菜单项时的工具栏中心textview

Question

在SO中阅读多个问题/答案后，我仍然在寻找答案 我的问题：在我的应用程序中，我使用工具栏，但根据片段/活动，您在工具栏菜单项中可能会更改，例如，在第一个屏幕上您将只看到一个Textview，在另一个片段中将会有主页箭头和溢出菜单有时有两个菜单图标。问题是标题以可用的空间为中心（工具栏空间 - 菜单空间）

这是我的工具栏xml：

AmCharts.addInitHandler(function(chart) {

  // do nothing if seriesField is not set and seriesValueField isn't set or is not an array
  if (chart.seriesField === undefined && (chart.seriesValueField === undefined || chart.seriesValueField.length === 0))
    return;

  // get graphs and dataProvider
  var graphs, dataSet;
  if (chart.type === "stock") {
    // use first panel
    if (chart.panels[0].stockGraphs === undefined)
      chart.panels[0].stockGraphs = [];
    graphs = chart.panels[0].stockGraphs;
    dataSet = chart.dataSets[0];

    // check if data set has fieldMappings set
    if (dataSet.fieldMappings === undefined)
      dataSet.fieldMappings = [];
  } else {
    if (chart.graphs === undefined)
      chart.graphs = [];
    graphs = chart.graphs;
    dataSet = chart;
  }

  // collect value fields for graphs that might already exist
  // in chart config
  var valueFields = {};
  if (graphs.length) {
    for (var i = 0; i < graphs.length; i++) {
      var g = graphs[i];
      if (g.id === undefined)
        g.id = i;
      valueFields[g.id] = g.valueField;
    }
  }

  // process data
  var newData = [];
  var dpoints = {};
  for (var i = 0; i < dataSet.dataProvider.length; i++) {
    // get row data
    var row = dataSet.dataProvider[i];
    var category = row[dataSet.categoryField];

    // create a data point
    if (dpoints[category] === undefined) {
      dpoints[category] = {};
      dpoints[category][dataSet.categoryField] = category;
      newData.push(dpoints[category]);
    }

    //add points and create graphs for each seriesField + seriesValueField combination
    chart.seriesValueFields.forEach(function(seriesValueField) {
      var series = chart.seriesField + ' ' + row[chart.seriesField] + ' ' + seriesValueField;

      // check if we need to generate a graph
      if (valueFields[series] === undefined) {
        // apply template
        var g = {};
        if (chart.seriesGraphTemplate !== undefined) {
          g = cloneObject(chart.seriesGraphTemplate);
        }
        g.id = series;
        g.valueField = series;
        g.title = series;

        // add to chart's graphs
        graphs.push(g);
        valueFields[series] = series;

        // add fieldMapping to data set on Stock Chart
        if (chart.type === "stock") {
          dataSet.fieldMappings.push({
            "fromField": series,
            "toField": series
          });
        }
      }

      // add series value field
      if (row[seriesValueField] !== undefined) {
        dpoints[category][series] = row[seriesValueField];
      }

    });
    // add the rest of the value fields (if applicable)
    for (var field in valueFields) {
      if (valueFields.hasOwnProperty(field) && row[field] !== undefined)
        dpoints[category][field] = row[field];
    }
  }

  // set data
  dataSet.dataProvider = newData;

  // function which clones object
  function cloneObject(obj) {
    if (null == obj || "object" != typeof obj) return obj;
    var copy = obj.constructor();
    for (var attr in obj) {
      if (obj.hasOwnProperty(attr)) copy[attr] = obj[attr];
    }
    return copy;
  }

}, ["serial", "stock"]);

// ...
AmCharts.makeChart("chartdiv", {
  // ...
  "seriesField": "day",
  "seriesValueFields": ["foo1", "foo3"],
  "seriesGraphTemplate": {
    "lineThickness": 2,
    "type": "smoothedLine",
    "useDataSetColors": false,
    "bullet": "round"
  },
  // ...
});

正如您所看到的，我尝试了contentInserStart但它没有改变任何东西。我还使用了relativelayout来中心textview。我需要它至少在API 19上工作（在我的手机上试试）。

即使我有菜单项，是否有解决方案将Textview置于栏中间？

修改
找不到任何解决方案我只是在RelativeLayout中添加了一个Image视图，就像主页按钮一样。
