如何以编程方式设置ImageView的高度和宽度

Question

我正在尝试将imageViews添加到线性布局中，如下所示：

LinearLayout.LayoutParams layoutParamsTV = new LinearLayout.LayoutParams(100, 100);
for( i = 0; i < 5; i++) {
    LinearLayout llv = new LinearLayout(this);
    llv.setOrientation(LinearLayout.VERTICAL);
    ImageView row1 = new ImageView(this);
    row1.getLayoutParams().height=50; // getting error here
}

如何设置ImageView的高度和宽度，我想在此imageView上再添加一个图像视图，该怎么做

Answer 1

试试这个：

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(640, 480); // width , height 

row1.setLayoutParams(params); // row1 is your ImageView
