android 动态 格局

动态增加布局：

private void addLayout(Context context) {		LinearLayout layout = new LinearLayout(context);		//设置宽高属性		LayoutParams fullParams = new LayoutParams(LayoutParams.MATCH_PARENT,				LayoutParams.MATCH_PARENT);		//设置布局方向		layout.setOrientation(LinearLayout.VERTICAL);		//设置背景颜色		layout.setBackgroundColor(getResources().getColor(R.color.black));		int id = 0;		//设置权重		LayoutParams weightParams = new LayoutParams(LayoutParams.MATCH_PARENT,				LayoutParams.MATCH_PARENT, 1.0f);		ArrayList<LinearLayout> list = new ArrayList<>();		for (int i = 0; i < line; i++) {			for (int j = 0; j < column; j++) {				LinearLayout tempLayout = new LinearLayout(context);				tempLayout.setBackgroundColor(getResources().getColor(R.color.gray));				tempLayout.setId(id++);//设置id				list.add(tempLayout);			}		}		LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,				LayoutParams.MATCH_PARENT, 1.0f);		params.setMargins(1, 0, 1, 0);		int index = 0;		for (int i = 0; i < line; i++) {			LinearLayout hor = new LinearLayout(context);			for (int j = 0; j < column; j++) {				hor.addView(list.get(index), params);				index++;			}			weightParams.setMargins(0, 1, 0, 1);			layout.addView(hor, weightParams);		}		setContentView(layout, fullParams);		LinearLayout linearLayout = (LinearLayout) findViewById(10);		linearLayout.setBackgroundColor(getResources().getColor(R.color.red));	}
