我有一个自定义 ListView ，我想做的是当用户在 lisview 中选择一个特定值时，它将在同一 Activity 的对话框中转到 editText。但它不会获得该值。这是我的代码
public void savedNotes(){
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View arg1, final int position,
long arg3) {
LayoutInflater li = LayoutInflater.from(context);
View promt = li.inflate(R.layout.prompt_saved_notes,null);
AlertDialog.Builder alerDialogBuilder = new AlertDialog.Builder(context);
alerDialogBuilder.setView(promt);
final EditText textfield1 = (EditText) promt.findViewById(R.id.edt_textfield);
alerDialogBuilder.setCancelable(false).setPositiveButton("saved",new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog,int id){
String itemString = list.getItemAtPosition(position).toString();
textfield1.setText(itemString);
}
}).setNegativeButton("cancel",new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog,int id){
dialog.cancel();
}
});
AlertDialog alertDialog = alerDialogBuilder.create();
alertDialog.show();
}
});
}
最佳答案
试试这个..
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View arg1, final int position,
long arg3) {
LayoutInflater li = LayoutInflater.from(context);
View promt = li.inflate(R.layout.prompt_saved_notes,null);
AlertDialog.Builder alerDialogBuilder = new AlertDialog.Builder(context);
alerDialogBuilder.setView(promt);
final EditText textfield1 = (EditText) promt.findViewById(R.id.edt_textfield);
String itemString = list.getItemAtPosition(position).toString();
textfield1.setText(itemString);
alerDialogBuilder.setCancelable(false).setPositiveButton("saved",new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog,int id){
}
}).setNegativeButton("cancel",new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog,int id){
dialog.cancel();
}
});
AlertDialog alertDialog = alerDialogBuilder.create();
alertDialog.show();
}
});
