Android 中使用代码动态网格布局，程序员深度学习
android:id="@+id/text_title"
style="@style/Text.Title"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:gravity=“center”
android:text=“业务功能介绍” />
android:id="@+id/layout_more"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:orientation=“vertical”
android:padding=“4dp” />
三、子条目xml布局文件
============
android:layout_width=“match_parent”
android:layout_height=“84dp”
android:layout_weight=“1.0”
android:clickable=“true” >
android:id="@+id/image_icon"
android:layout_width=“wrap_content”
android:layout_height=“wrap_content”
android:layout_gravity=“center_horizontal”
android:layout_marginTop=“16dp”
android:duplicateParentState=“true”
android:src="@drawable/ic_department_01_normal" />
android:id="@+id/text_title"
android:layout_width=“wrap_content”
android:layout_height=“wrap_content”
android:layout_gravity=“center_horizontal|bottom”
android:background="@null"
android:layout_marginBottom=“6dp”
android:gravity=“center”
android:duplicateParentState=“true”
android:textColor="@drawable/text_service_color"
android:textSize=“14dp” />
如图： 
四、java代码动态布局
============
/**
-
@author gao_chun
*/
public class MainActivity extends Activity implements OnClickListener{
private ViewGroup mMoreLayout; //父布局容器(动态加载的资源图片和文字等布局都将添加在其里面)
/* (non-Javadoc)
- @see app.ui.TitleActivity#onCreate(android.os.Bundle)
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initUI(); //保证启动方法的唯一性
}
private void initUI() {
setContentView(R.layout.activity_main);
//找到该容器（这里的控件为LinearLayout，转换为ViewGroup是因为ViewGroup是容器的基类）
mMoreLayout = (ViewGroup) findViewById(R.id.layout_more);
//由于文字也是动态生成，使用android中array文件定义资源文件，并取出
final String[] categories = getRe
sources().getStringArray(R.array.categories);
final int size = categories.length; //String[]的长度
final int rowCount = size / 3; //需要布局的行数(每行三个)
/**
-
动态添加布局方法封装
-
参数 1.父容器 2.资源文字数组 3.从第几个开始 4.行数
*/
fillViews(mMoreLayout, categories, 0, rowCount);
}
private void fillViews(ViewGroup layout, String[] categories, int start, int end) {
// 表格第一条线
View.inflate(this, R.layout.layout_line_horizonal, layout);
for (int i = start; i < end; i++) {
//找到索引，便于根据索引添加图片文件和文字
final int firstIndex = i * 3;
final int secondIndex = i * 3 + 1;
final int thirdIndex = i * 3 + 2;
final String firstCategory = categories[firstIndex];
final String secondCategory = categories[secondIndex];
final String thirdCategory = categories[thirdIndex];
//这里控制的是加载本地图片，通过应用包命找到 有规则命名的图片资源文件
//—>因为这里有两种效果，一是默认的图片，二是按下触发后的图片和文字
final int firstDrawableNormal = getResources().getIdentifier(String.format(“ic_department_%02d_normal”,
firstIndex + 1),“drawable”,getApplicationContext().getPackageName());
final int secondDrawableNormal = getResources().getIdentifier(String.format(“ic_department_%02d_normal”,
secondIndex + 1),“drawable”,getApplicationContext().getPackageName());
final int thirdDrawableNormal = getResources().getIdentifier(String.format(“ic_department_%02d_normal”,
thirdIndex + 1),“drawable”,getApplicationContext().getPackageName());
final int firstDrawablePressed = getResources().getIdentifier(String.format(“ic_department_%02d_pressed”,
firstIndex + 1),“drawable”,getApplicationContext().getPackageName());
final int secondDrawablePressed = getResources().getIdentifier(String.format(“ic_department_%02d_pressed”,
secondIndex + 1),“drawable”,getApplicationContext().getPackageName());
final int thirdDrawablePressed = getResources().getIdentifier(String.format(“ic_department_%02d_pressed”,
thirdIndex + 1),“drawable”,getApplicationContext().getPackageName());
//这里是将上面找到的 默认图片 和 按下时的图片 放入到 StateListDrawable缓存中
final StateListDrawable firstDrawable = new StateListDrawable();
firstDrawable.addState(new int[]{android.R.attr.state_pressed}, getResources().getDrawable(firstDrawablePressed));
firstDrawable.addState(new int[]{}, getResources().getDrawable(firstDrawableNormal));
final StateListDrawable secondDrawable = new StateListDrawable();
secondDrawable.addState(new int[]{android.R.attr.state_pressed}, getResources().getDrawable(secondDrawablePressed));
secondDrawable.addState(new int[]{}, getResources().getDrawable(secondDrawableNormal));
final StateListDrawable thirdDrawable = new StateListDrawable();
thirdDrawable.addState(new int[]{android.R.attr.state_pressed}, getResources().getDrawable(thirdDrawablePressed));
thirdDrawable.addState(new int[]{}, getResources().getDrawable(thirdDrawableNormal));
// 父布局
final LinearLayout linearLayout = new LinearLayout(this);
// 第一个子布局
View.inflate(this, R.layout.layout_line_vertical, linearLayout);
View.inflate(this, R.layout.layout_department, linearLayout);
View.inflate(this, R.layout.layout_line_vertical, linearLayout);
DrawableNormal));
// 父布局
final LinearLayout linearLayout = new LinearLayout(this);
// 第一个子布局
View.inflate(this, R.layout.layout_line_vertical, linearLayout);
View.inflate(this, R.layout.layout_department, linearLayout);
View.inflate(this, R.layout.layout_line_vertical, linearLayout);
