问题描述

我尝试用 input.setImeOptions(EditorInfo.IME_ACTION_DONE)设置在softkeyboard完成按钮;

但完成按钮根本不显示在softkeyboard。

任何建议吗?

 公共无效改性的(INT位置){
    AlertDialog.Builder警报=新AlertDialog.Builder(MainActivity.this);
    alert.setTitle(Modifica);
    EditText上输入=新的EditText(MainActivity.this);
    input.setImeOptions(EditorInfo.IME_ACTION_DONE);
    alert.setView(输入);
    最后编辑值= input.getText();
    alert.setPositiveButton(OK,新DialogInterface.OnClickListener(){
        公共无效的onClick(DialogInterface对话,诠释whichButton){
            Toast.makeText(getApplicationContext(),价值,Toast.LENGTH_LONG).show();
        }
    });

    alert.setNegativeButton(取消,新DialogInterface.OnClickListener(){
        公共无效的onClick(DialogInterface对话,诠释whichButton){
        // 取消。
        }
    });
    alert.show();
}
 

解决方案

这可能是因为你的输入域不是单成荫。

尝试添加

  input.setSingleLine();
 

和您将看到pressing键盘将实际执行一个完成动作的动作键(即关闭键盘)

I try to set the "Done" button on the softkeyboard by using input.setImeOptions(EditorInfo.IME_ACTION_DONE);

but the "Done" button simply does not show on the softkeyboard.

Any suggestion please?

public void modif(int position) {
    AlertDialog.Builder alert = new  AlertDialog.Builder(MainActivity.this);
    alert.setTitle("Modifica");
    EditText input = new EditText(MainActivity.this);
    input.setImeOptions(EditorInfo.IME_ACTION_DONE);
    alert.setView(input);
    final Editable value = input.getText();
    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {  
        public void onClick(DialogInterface dialog, int whichButton) {
            Toast.makeText(getApplicationContext(), value,   Toast.LENGTH_LONG).show();
        }
    });

    alert.setNegativeButton("Cancel", new     DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
        // Canceled.
        }
    });
    alert.show();                   
}

解决方案

It's probably because your input field is not single-lined.

Try adding

input.setSingleLine();

And you will see that pressing the action key of the keyboard will actually perform a 'done' action (i.e close the keyboard)

See http://developer.android.com/reference/android/view/inputmethod/EditorInfo.html#IME_ACTION_DONE
