动态设置视图大小

private void setLinearLayoutParams(View imageView) {
    if (mScreenSize == 0 )
        mScreenSize = getScreenSize();

    int width = ViewGroup.LayoutParams.MATCH_PARENT;

    int height = 0;
    if (mScreenSize <= 7)
        height = LayoutConstants.sVerVideoImgHeight + 165;
    else
        height = LayoutConstants.sVerVideoImgHeight + 115;

    ViewGroup.LayoutParams params = imageView.getLayoutParams();
    if (params == null) {
        params = new ViewGroup.LayoutParams(width, height);
        imageView.setLayoutParams(params);
    } else {
        params.width = width;
        params.height = height;
    }
}



动态根据weight添加

LinearLayout.LayoutParams paramsItemView = new LinearLayout.LayoutParams(
        0,
        ViewGroup.LayoutParams.WRAP_CONTENT, 1);
LinearLayout.addView(convertView,paramsItemView);
