我在EditText
的每一行中都有一个ListView
。出于某种原因,当我点击EditText时,它会短暂地获得焦点但然后立即失去它。
我尝试过这些东西:
listView.setItemsCanFocus(true);
editText.setFocusable(true);
虽然EditText
是(简要)重点关注,但Enter
键表示Next
且auto-correct bar
存在。当它失去焦点时,软键盘会保持向上,但Enter
键变为Return Arrow
,auto-correct bar
消失。

如果您希望列表项目成为焦点,那么它非常直接:
使列表视图无法调焦,并说它的焦点是afterDescendants
,这使得EditText
和其他可聚焦项目成为焦点。
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:descendantFocusability="afterDescendants"
android:focusable="false" />

EditText
内的 ListView
非常棘手。如果可能的话,我建议你像瘟疫一样避开它们。当我弄乱他们的时候,this answer虽然很有帮助。如果您只有一些项目,则可以随时使用ScrollView
。

我知道这个问题很老,但我今天也在与EditText和ListView作斗争。我认为失去焦点问题的时间或更新数据集是行的结束。
所以,我创建了一个Activity并动态添加了我需要的控件。在这个例子中,我添加了两个控件:textview和edittext。
首先,我创建一个类作为控件的“容器”,然后将控件放在ScrollView上。
layout.xml文件:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/llMain"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/tvHeader"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<ScrollView
android:id="@+id/svMain"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="@+id/llForm"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</LinearLayout>
“containter”类:
import android.widget.EditText;
public class RespostasArray {
private int pergunta;
private int formulario;
private int form_coord;
private int coordenada;
private int form_resposta;
private String questao;
private String resposta;
private EditText respostaEdit;
public RespostasArray() {
respostaEdit = null;
}
public int getPergunta() {
return pergunta;
}
public void setPergunta(int pergunta) {
this.pergunta = pergunta;
}
public int getFormulario() {
return formulario;
}
public void setFormulario(int formulario) {
this.formulario = formulario;
}
public int getForm_coord() {
return form_coord;
}
public void setForm_coord(int form_coord) {
this.form_coord = form_coord;
}
public int getCoordenada() {
return coordenada;
}
public void setCoordenada(int coordenada) {
this.coordenada = coordenada;
}
public int getForm_resposta() {
return form_resposta;
}
public void setForm_resposta(int form_resposta) {
this.form_resposta = form_resposta;
}
public String getQuestao() {
return questao;
}
public void setQuestao(String questao) {
this.questao = questao;
}
public String getResposta() {
return resposta;
}
public void setResposta(String resposta) {
this.resposta = resposta;
}
public EditText getRespostaEdit() {
return respostaEdit;
}
public void setRespostaEdit(EditText respostaEdit) {
this.respostaEdit = respostaEdit;
}
}
所以,主要活动:

} else {

}
}
我希望它有所帮助。
