回答1:

You can use DecimalFormat

DecimalFormat format = new DecimalFormat("##.#");
String formattedText = format.format(025.0);
editText.setText(formattedText);

You will get result in EditText as 25.0

you can set it in xml file. Like

<EditText
    android:id="@+id/editText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/imageView1"
    android:layout_below="@+id/imageView1"
    android:layout_marginLeft="20dp"
    android:layout_marginTop="54dp"
    android:ems="10"
    android:inputType="numberDecimal" >
