Question

嘿，我将在下面的代码中简要介绍一下我的操作：我创建一个ViewStub（Vs）并将其添加到RelativeLayout（R1）。然后我想在同一个RL中添加一个新的V，所以我创建了stub2并将其添加到rl。然后我引用第一个和第二个Vs（rlInf1，rlInf2）的R1（它是inflatet）然后我设置Rl.Layoutparams，以便rlInf2应该低于rlInf1，但它们是重叠的。如何设置LayoutParams以使新ViewStub低于旧ViewStub？任何想法？

（我没有在XML中添加ViewStub，而是在Java代码中添加）

//Löschen des Standard-Tv
            TextView tv = (TextView) findViewById(R.id.tvNoContentInfo);
            RelativeLayout rl = (RelativeLayout) findViewById(R.id.Layout_ContentInfo);
            rl.removeView(tv);
            //Erstellen eines ViewStubs
            ViewStub stub1 = new ViewStub(this);
            //zum richtigen Layout hinzufügen
            rl.addView(stub1);
            stub1.setLayoutResource(R.layout.routen_navi_infocontent);
            //Referenz zum eingefügten Layout herstellen
            View inflated = stub1.inflate();
            //Zugriff auf Inhalt des zufor referenzierten Layouts
            TextView myTextView = (TextView) inflated.findViewById(R.id.tvHeaderInfocontent);
            myTextView.setText("hey");
            stub1.setId(View.generateViewId());
            stub1.setInflatedId(stub1.getId());
            RelativeLayout rlInf1 = (RelativeLayout) inflated.findViewById(R.id.Layout_infocontent);

            ViewStub stub2 = new ViewStub(this);
            //zum richtigen Layout hinzufügen
            rl.addView(stub2);
            stub2.setLayoutResource(R.layout.routen_navi_infocontent);
            //Referenz zum eingefügten Layout herstellen
            View inflated2 = stub2.inflate();
            RelativeLayout rlInf2 = (RelativeLayout) inflated2.findViewById(R.id.Layout_infocontent);
            RelativeLayout.LayoutParams p= new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            p.addRule(RelativeLayout.BELOW,rlInf1.getId());
            rlInf2.setLayoutParams(p);

将视图扩展到ViewStub后，ViewStub消失了，因此更改其中的ID毫无用处。您需要在膨胀的视图上更改它。所以改变

stub1.setId(View.generateViewId());

到

inflated.setId(View.generateViewId());

并将最后两行更改为：

    p.addRule(RelativeLayout.BELOW,inflated.getId());
    inflated2.setLayoutParams(p);

此外，您可能希望从LayoutParams视图中抓取现有的inflated而不创建新的ViewStubs，否则您将最终覆盖所有现有的。{/ p> 顺便说一句：我必须假设增加ViewStub和即时通货膨胀只是对某事而不是实际流动的考验，对吧？： - ）

此外：是的，您可以在不使用View inflated = LayoutInflater.from(this).inflate(R.layout.routen_navi_infocontent, rl, false); inflated.setId(View.generateViewId()); rl.addView(inflated); View inflated2 = LayoutInflater.from(this).inflate(R.layout.routen_navi_infocontent, rl, false); RelativeLayout.LayoutParams p= new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); p.addRule(RelativeLayout.BELOW,inflated.getId()); inflated2.setLayoutParams(p); rl.addView(inflated2); TextView myTextView = (TextView) inflated.findViewById(R.id.tvHeaderInfocontent); myTextView.setText("hey");

的情况下添加布局

var text = "I'm very upset, very distress, very agitated, very annoyed and very pissed";
var regex = /very/;
var synonyms = ["extremely", "exceedingly", "exceptionally", "especially", "tremendously"];

以编程方式将ViewStub添加到RelativeLayout，而不是在第一个
