Question

我必须以编程方式添加图像，但是，我试图复制并粘贴相同的代码，但使用不同的图像文件。这不起作用，相反它只是选择了最后一张图片＆＃34;添加＆＃34;。这是我添加一张图片的代码：

String flag = getIntent().getStringExtra("IMAGE");
    int id = getResources().getIdentifier(flag, "drawable", getPackageName());

    LinearLayout linearLayout= new LinearLayout(this);
    linearLayout.setOrientation(LinearLayout.VERTICAL);
    linearLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.MATCH_PARENT));
    ImageView imageView = new ImageView(this);
    imageView.setImageResource(id);
    imageView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.WRAP_CONTENT));
    linearLayout.addView(imageView);
    setContentView(linearLayout);

这是我的＃34;复制并粘贴＆＃34;：

String pic = getIntent().getStringExtra("IMAGECITY");
    int id1 = getResources().getIdentifier(pic, "drawable", getPackageName());

    LinearLayout linearLayout1= new LinearLayout(this);
    linearLayout1.setOrientation(LinearLayout.VERTICAL);
    linearLayout1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.MATCH_PARENT));
    ImageView imageView1 = new ImageView(this);
    imageView1.setImageResource(id1);
    imageView1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.WRAP_CONTENT));
    linearLayout1.addView(imageView1);
    setContentView(linearLayout1);

任何人都可以帮我解决添加另一张图片并将其放在底部吗？

在Selvin的帮助下，我删除了：

LinearLayout linearLayout1= new LinearLayout(this);
linearLayout1.setOrientation(LinearLayout.VERTICAL);
linearLayout1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
        LinearLayout.LayoutParams.MATCH_PARENT));

并使用linearLayout1将变量更改为linearLayout。
