布局很简单，主要是id为layout_container的一个LinearLayout作为父布局。
横向的线条和纵向的线条布局也很简单：
<View xmlns:android=“http://schemas.android.com/apk/res/android”
android:layout_width=“match_parent”
android:layout_height=“1px”
android:background="#cbcbcb" />
<View xmlns:android=“http://schemas.android.com/apk/res/android”
android:layout_width=“1px”
android:layout_height=“match_parent”
android:background="#cbcbcb" />
下面是动态生成布局的实现方式：
private void initUI() {
setContentView(R.layout.activity_main);
//setTitle(R.string.button_service_upload_picture);
//showBackwardView(R.string.button_backward, true);
//showForwardView(R.string.button_upload,true);
//最顶层父布局
mLayout = (ViewGroup) findViewById(R.id.layout_container);
final int count = 9; //9格
final int rowCount = (count + 2) / 3;
for (int i = 0; i < rowCount; i++) {
if (i != 0) {
//加载横向布局线条
View.inflate(this, R.layout.layout_line_horizonal, mLayout);
}
//创建布局对象，设置按下颜色
final LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setBackgroundResource(R.drawable.row_select

or);
for (int j = 0; j < 3; j++) {
if (j != 0) {
//加载内层纵向布局线条
View.inflate(this, R.layout.layout_line_vertical, linearLayout);
}
ImageButton imageButton = new ImageButton(this);
imageButton.setBackgroundResource(R.drawable.row_selector);
imageButton.setTag(TAG);
imageButton.setOnClickListener(this);
imageButton.setEnabled(false);
LinearLayout.LayoutParams layoutParams =
new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f);
//添加到linearLayout布局中
linearLayout.addView(imageButton, layoutParams);
//将imageButton对象添加到列表
mImageButtonList.add(imageButton);
}
DisplayManager manager = DisplayManager.getInstance();
LayoutParams layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, manager.dipToPixel(100));
//将View添加到总父布局
mLayout.addView(linearLayout, layoutParams);
}
//外层设置ImageButton属性
final ImageButton currentImageButton = mImageButtonList.get(mCurrent);
currentImageButton.setImageResource(R.drawable.ic_add_picture);
currentImageButton.setScaleType(ScaleType.CENTER);
currentImageButton.setEnabled(true);
}
