单个屏幕中的大量Button和textview

标签: android arrays button textview

我想实现一个应用程序来存储有关冰柜内容的信息。 我开发的第一个布局是5" floor" ,在任何楼层都有12个Button和12个TextView,但结果是12x5 = 60个按钮和60个textview。

layout 我认为这种布局有很多资源......或者不是吗? 代码实现起来更简单,但性能不好!(我认为)。

这是第一个实现的代码:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:scrollbarStyle="insideOverlay"
    android:scrollbars="vertical" >

    <LinearLayout
        android:id="@+id/LinearLayout0"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:background="@drawable/a9p_09_11_00943" >

        <GridLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:columnCount="8"
            android:orientation="horizontal"
            android:rowCount="4" >

            <!-- prima riga  P1 R1 -->

            <ImageButton
                android:id="@+id/btnP1C1R1"
                android:layout_column="1"
                android:layout_gravity="left|top"
                android:layout_row="0"
                android:background="@drawable/add_64" android:contentDescription="@string/store_add" />

            <ImageButton
                android:id="@+id/btnP1C2R1"
                android:layout_column="3"
                android:layout_gravity="left|top"
                android:layout_row="0"
                android:background="@drawable/add_64" android:contentDescription="@string/store_add"/>

            <ImageButton
                android:id="@+id/btnP1C3R1"

                android:layout_row="0"
                android:background="@drawable/add_64" android:contentDescription="@string/store_add" />

            <TextView

                android:textAppearance="?android:attr/textAppearanceLarge" />

                android:layout_row="0"
                android:text="@string/store_void"
                android:textAppearance="?android:attr/textAppearanceLarge" />

            <TextView

                android:textAppearance="?android:attr/textAppearanceLarge" />

            <TextView

            <!-- seconda riga  P1 R4 -->

            <ImageButton
                android:id="@+id/btnP1C1R4"

                android:layout_row="3"
                android:background="@drawable/add_64" android:contentDescription="@string/store_add" />

            <ImageButton
                android:id="@+id/btnP1C3R4"
                android:layout_column="5"
                android:layout_gravity="left|top"
                android:layout_row="3"
                android:background="@drawable/add_64" android:contentDescription="@string/store_add" />

            <TextView
                android:id="@+id/txtP1C1R4"

                android:textAppearance="?android:attr/textAppearanceLarge" />

            <TextView
                android:id="@+id/txtP1C2R4"
                android:layout_column="4"
                android:layout_width="@dimen/size_txt_view"
                android:layout_gravity="left|center_vertical"
                android:layout_row="3"
                android:text="@string/store_void"
                android:textAppearance="?android:attr/textAppearanceLarge" />

            <TextView
                android:id="@+id/txtP1C3R4"
                android:layout_column="6"
                android:layout_width="@dimen/size_txt_view"
                android:layout_gravity="left|center_vertical"
                android:layout_row="3"
                android:text="@string/store_void"
                android:textAppearance="?android:attr/textAppearanceLarge" />

            <TextView
                android:id="@+id/textView1"
                android:layout_column="0"
                android:layout_row="0"
                android:layout_gravity="left|center_vertical"
                android:text="@string/store_4" />
            <TextView
                android:id="@+id/textView2"
                android:layout_column="0"
                android:layout_row="1"
                android:layout_gravity="left|center_vertical"
                android:text="@string/store_3" />
            <TextView
                android:id="@+id/textView3"
                android:layout_column="0"
                android:layout_row="2"
                android:layout_gravity="left|center_vertical"
                android:text="@string/store_2" />
            <TextView
                android:id="@+id/textView4"
                android:layout_column="0"
                android:layout_row="3"
                android:layout_gravity="left|center_vertical"
                android:text="@string/store_1" />
        </GridLayout>

    </LinearLayout>

第二个想法是自定义ListView。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/a9p_09_11_00943">

    <RelativeLayout
        android:id="@+id/RelativeLayout0"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true">

        <ListView
            android:id="@+id/listView"
            android:layout_width="wrap_content"
            android:layout_height="fill_parent"
            android:layout_alignParentRight="true" >
        </ListView>

    </RelativeLayout>

</RelativeLayout>

自定义项目包含12个buttom和12个textview,如下所示:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"

    android:scrollbars="vertical" >

    <LinearLayout
        android:id="@+id/LinearLayout0"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:background="@drawable/a9p_09_11_00943" >

        <GridLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:columnCount="8"
            android:orientation="horizontal"
            android:rowCount="4" >

            <!-- prima riga  P1 R1 -->

            <ImageButton
                android:id="@+id/btnP1C1R1"
                android:layout_column="1"
                android:layout_gravity="left|top"
                android:layout_row="0"
                android:background="@drawable/add_64" android:contentDescription="@string/store_add" />

            <ImageButton
                android:id="@+id/btnP1C2R1"
                android:layout_column="3"
                android:layout_gravity="left|top"
                android:layout_row="0"
                android:background="@drawable/add_64" android:contentDescription="@string/store_add"/>

            <ImageButton
                android:id="@+id/btnP1C3R1"

                android:layout_row="0"
                android:background="@drawable/add_64" android:contentDescription="@string/store_add" />

            <TextView

                android:layout_column="2"
                android:layout_gravity="left|center_vertical"
                android:layout_row="0"
                android:text="@string/store_void"
                android:textAppearance="?android:attr/textAppearanceLarge" />

            <TextView

                android:textAppearance="?android:attr/textAppearanceLarge" />

            <TextView
                android:id="@+id/txtP1C3R1"
                android:layout_width="@dimen/size_txt_view"
                android:layout_column="6"
                android:layout_gravity="left|center_vertical"
                android:layout_row="0"
                android:text="@string/store_void"

            <!-- seconda riga  P1 R2 -->

我有可能增加很多楼层,更多的是5! 但是实现代码有很多困难: 1)当用户点击项目(冷冻地板)时,如何为所有12个按钮实现 button.setOnClickListener

2)适配器内 getView 的性能是快还是慢?

另一个想法是创建5片段,并在每个片段内部构建一个xml whith 12按钮和12个textview。 可能这个想法还是更复杂? 还有其他想法吗? 感谢。

修改

我尝试了另一种方法,通过对xml充气:

容器:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/LinearLayout0"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:scrollbars="vertical" >

</LinearLayout>

代码:

private static final int[] BUTTON_IDS_P1 = {
            R.id.btnP1C1R1,
            R.id.btnP1C1R2, 
            R.id.btnP1C1R3,
            R.id.btnP1C1R4,
            R.id.btnP1C2R1,
            R.id.btnP1C2R2, 
            R.id.btnP1C2R3,
            R.id.btnP1C2R4,
            R.id.btnP1C3R1,
            R.id.btnP1C3R2,
            R.id.btnP1C3R3,
            R.id.btnP1C3R4
        };

        for(int i = 0; i < 5; i++){
                        final LayoutInflater inflater = (LayoutInflater) appContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

                        View child =  inflater.inflate(R.layout.ripiano_frigo, null);
                        child.setId(i);
                        lLayout = (LinearLayout) rootView.findViewById(R.id.LinearLayout0);
                        lLayout.addView(child);
    buttons = new ArrayList<ImageButton>(BUTTON_IDS_P1.length);
                    int idt=0;
                    for(int id : BUTTON_IDS_P1) {
                        ImageButton button = (ImageButton)rootView.findViewById(id);
                        //button.setOnClickListener(this); // maybe
                        MyTag myTag = new MyTag(idt, id,TEXTVIEW_IDS_P1[idt++], 0, 0);
                        button.setTag(myTag);

                        button.setOnClickListener(new View.OnClickListener() {

                            @Override
                            public void onClick(View v) {
}

对于第一组按钮(12),一切正常,但如何配置另一组?哪个是第二组按钮的ID?

使用第一层创建布局并动态扩展布局并创建楼层。
