寫在這裡以作筆記。

第一種：佈局檔案中新增

佈局檔案中：
<android.support.percent.PercentFrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <EditText
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/StartDate"
            android:hint="點選選擇開始日期"
            android:layout_gravity="left"
            />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="---"
            android:layout_gravity="center"/>
        <EditText
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/EndDate"
            android:hint="點選選擇結束日期"
            android:layout_gravity="right"/>
    </android.support.percent.PercentFrameLayout>
程式碼實現：
 StartDate = (EditText) findViewById(R.id.StartDate);
   EndDate = (EditText) findViewById(R.id.EndDate);
StartDate.setText(year + "年" + (month + 1) + "月" + dayOfMonth + "日")
 

第二種：程式碼實現新增

先新增ID
<item name="TextView_Inspection_Sites" type="id"/>
    <item name="TextView_Inspection_Param" type="id"/>
程式碼實現新增：
TextView TextView_Inspection_Sites=new TextView(this);
                TextView_Inspection_Sites.setId(R.id.TextView_Inspection_Sites);
                TextView_Inspection_Sites.setText("檢修部位：" + list.get(i).getInspectionSites().getSiteName());
                TextView_Inspection_Sites.setTextSize(18);
                ViewGroup.LayoutParams layout_TextView_Inspection_Sites=new AppBarLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
                TextView_Inspection_Sites.setLayoutParams(layout_TextView_Inspection_Sites);
                lineLayout.addView(TextView_Inspection_Sites);

                TextView TextView_Inspection_Param=new TextView(this);
                TextView_Inspection_Param.setId(R.id.TextView_Inspection_Param);
                TextView_Inspection_Param.setText("巡檢內容：" + list.get(i).getInspectionParams().getPhenomenon());
                TextView_Inspection_Param.setTextSize(18);
                LinearLayout.LayoutParams layout_TextView_Inspection_Param=new AppBarLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
                TextView_Inspection_Sites.setLayoutParams(layout_TextView_Inspection_Param);
                lineLayout.addView(TextView_Inspection_Param);
 

第三種：在程式碼中實現動態新增

佈局檔案中新增如下程式碼：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:layout_marginTop="10dp"
        android:background="@color/gray"/>
</LinearLayout>
點選事件中新增如下程式碼：

LinearLayout lin=(LinearLayout)getLayoutInflater().inflate(R.layout.aline, lineLayout,false);
lineLayout.addView(lin);
本例中新增的是一條線
