一、說明
新增檢視檔案的時候有兩種方式:1、通過在xml檔案定義layout；2、java程式碼編寫

二、前言說明

1.構造xml檔案

2.LayoutInflater

提到addview，首先要了解一下LayoutInflater類。這個類最主要的功能就是實現將xml表述的layout轉化為View的功能。為了便於理解，我們可以將它與findViewById()作一比較，二者都是例項化某一物件，不同的是findViewById()是找xml佈局檔案下的具體widget控制元件例項化，而LayoutInflater找res/layout/下的xml佈局檔案來例項化的。

(1)建立

LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);或

LayoutInflater inflater = LayoutInflater.from(Activity.this);或

LayoutInflater inflater = getLayoutInflater();

這三種方法本質是相同的。

(2)inflate()

用LayoutInflater.inflate() 將LayOut檔案轉化成VIew。

View view = inflater.inflate(R.layout.block_gym_album_list_item, null);

3.新增檢視檔案

三、步驟
1、通過在xml檔案定義layout(block_gym_album_list_item.xml)

<linearlayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:padding="5dp">

        <imageview 
          android:id="@+id/iv_head_album"
          android:layout_width
 
="wrap_content"
          android:layout_height="wrap_content"
          android:src="@drawable/defaulthead">
        </imageview>
</linearlayout>

activity_dynamic

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/ll_parent"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <include
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            layout="@layout/block_head_back">
        </include>
    </linearlayout>

3、MainActivity

        //定義子View中兩個元素的佈局 
        ViewGroup.LayoutParams vlp = new ViewGroup.LayoutParams( 
                ViewGroup.LayoutParams.WRAP_CONTENT,

        tv1.setText("姓名:"); 
        tv2.setText("李四"); 
        tv2.setPadding(calculateDpToPx(50), 0, 0, 0);//設定邊距 
        view.addView(tv1);//將TextView 新增到子View 中 
        view.addView(tv2);//將TextView 新增到子View 中 
        return view; 
    }

    private int calculateDpToPx(int padding_in_dp){ 
        final float scale = getResources().getDisplayMetrics().density; 
        return  (int) (padding_in_dp * scale + 0.5f); 
    } 


    @Override
    public void onClick(View v) {
        // TODO 控制元件單擊事件
        switch (v.getId()) {
