我有一个带有一点“数量”editext 的 DateTimePicker，我保存了 Sharedpref 但由于某种原因，如果我“触摸”EditText 并手动输入数量，文本是黑色的并且不会传输到 TextView，如果使用imagebuttonsincrease和decreaseeditText 将按预期工作。如果我以这种方式输入日期和时间，虽然它确实有效，但我错过了什么？

ImageButton increase = (ImageButton)mDateTimeDialogView.findViewById(R.id.increase);
increase.setOnClickListener(new OnClickListener(){
public void onClick(View v){


amountt++;
amountText = Integer.toString(amountt);
amountedit.setHint(amountText);
amnt.setText(amountText);



editor.putString("numbers", amountText);
editor.commit();

    }
});
ImageButton decrease = (ImageButton)mDateTimeDialogView.findViewById(R.id.decrease);
decrease.setOnClickListener(new OnClickListener(){

    public void onClick(View v){




      amountt--;
      amountText = Integer.toString(amountt);
      amountedit.setHint(amountText);
      amnt.setText(amountText);

      editor.putString("numbers", amountText);
      editor.commit();

    }
});

相关的 EditText 信息

amountedit=(EditText)mDateTimeDialogView.findViewById(R.id.amountedit);

它显示的 TextView

amnt = (TextView)findViewById(R.id.amountText);

EditText 的 XML

<EditText
    android:id="@+id/amountedit"
    android:layout_width="50dp"
    android:key = "amntkey"
    android:layout_height="wrap_content"
    android:layout_above="@+id/linearLayout1"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="62dp"
    android:ems="10"
    android:inputType="number"
    android:persistent="true" />

您的代码不清楚，您应该发布有关您正在谈论的 EditText 的代码。

顺便说一句，要得到你想要的，你可以尝试做 Sharedpref 的编辑和提交

当你的 EditText 的文本发生变化时，虽然它的设计很糟糕......

您需要一个文本更改侦听器

EditText.addTextChangedListener(new TextWatcher()
{
  @Override
  public void onTextChanged(CharSequence s, int start, int before, int count)
  {}

  @Override
  public void beforeTextChanged(CharSequence s, int start, int count, int after)
  {}

  @Override
  public void afterTextChanged(Editable s)
  {}
});
