SAPUI5 Set Focus on Input Field
提问by Daeron
i have the following Problem:
我有以下问题：
I have 2 XML Views with a few input fields and at navigation to the second view the focus should be on the 5th(ID = "RueckmeldeNr") field.
我有 2 个带有几个输入字段的 XML 视图，在导航到第二个视图时，焦点应该放在第 5 个（ID = "RueckmeldeNr"）字段上。
I tried several things but nothing worked..
If i use the jQuery delayedCall the focus shortly flashes on the input field but is instantly set to the NavBack Button in the upper left corner.
Do i use the method false or forget something? How can i solve this?
我尝试了几件事，但没有任何效果。如果我使用 jQuery delayCall，焦点会在输入字段上短暂闪烁，但会立即设置为左上角的 NavBack 按钮。
我是使用 false 方法还是忘记了什么？我该如何解决这个问题？
onAfterRendering : function(oEvent) {
oInputRueck = this.getView().byId("RueckmeldeNr");
// this.getView().byId("RueckmeldeNr").focus();
// this.getView().byId("RueckmeldeNr").$().focus();
// jQuery.sap.delayedCall(200, this, function() {
// //this.getView().byId("RueckmeldeNr").focus();
// oInputRueck.focus();
// });
// var oFocusInfo = this.getView().byId("RueckmeldeNr").getFocusInfo()
// this.getView().byId("RueckmeldeNr").applyFocusInfo(oFocusInfo);
jQuery.sap.delayedCall(0, this, function() {
oInputRueck.focus();
});
},
I hope you can help me!
Thank you

Just a suggestion:
只是一个建议：
You could set focus to the required field in the view (or where ever you define it).
您可以将焦点设置到视图中的所需字段（或您定义它的任何地方）。
For example, in view1 you define:
例如，在 view1 中定义：
var oInput = new sap.m.Input({id: "inputID"})
.addEventDelegate({
onAfterRendering: function(){
oInput.focus();
}
});
and then, when you call the view, the focus should be set to the required field automatically.
然后，当您调用视图时，焦点应自动设置为必填字段。

Answer is solved by myself.
答案是我自己解决的。
I just put the delayedCall on 500 miliseconds and it worked.
我只是将 delayCall 设置为 500 毫秒并且它起作用了。
jQuery.sap.delayedCall(500, this, function() {
this.getView().byId("RueckmeldeNr").focus();
});
