Drawable x = getResources().getDrawable(R.drawable.x);
x.setBounds(0, 0, x.getIntrinsicWidth(), x.getIntrinsicHeight());
mEditText.setCompoundDrawables(null, null, x, null);

式中x为:

Drawable x = getResources().getDrawable(R.drawable.x);
x.setBounds(0, 0, x.getIntrinsicWidth(), x.getIntrinsicHeight());
mEditText.setCompoundDrawables(null, null, x, null);

式中x为:

如果你碰巧使用DroidParts，我刚刚添加了clearleedittext。

下面是自定义背景和清除图标设置为abs__ic_clear_holo_light的效果:

下面是带有小部件的完整库: https://github.com/opprime/EditTextField

要使用它，你应该添加依赖:

compile 'com.optimus:editTextField:0.2.0'

在layout.xml文件中，你可以设置小部件:

xmlns:app="http://schemas.android.com/apk/res-auto"

app:clearButtonMode,can有这样的值: 从来没有 总是 whileEditing unlessEditing 应用:clearButtonDrawable

实际例子:

    <EditText
    android:id="@+id/idSearchEditText"
    android:layout_width="match_parent"
    android:layout_height="@dimen/dimen_40dp"
    android:drawableStart="@android:drawable/ic_menu_search"
    android:drawablePadding="8dp"
    android:ellipsize="start"
    android:gravity="center_vertical"
    android:hint="Search"
    android:imeOptions="actionSearch"
    android:inputType="text"
    android:paddingStart="16dp"
    android:paddingEnd="8dp"
/>

EditText mSearchEditText = findViewById(R.id.idSearchEditText);
mSearchEditText.addTextChangedListener(this);
mSearchEditText.setOnTouchListener(this);


@Override
public void afterTextChanged(Editable aEditable) {
    int clearIcon = android.R.drawable.ic_notification_clear_all;
    int searchIcon = android.R.drawable.ic_menu_search;
    if (aEditable == null || TextUtils.isEmpty(aEditable.toString())) {
        clearIcon = 0;
        searchIcon = android.R.drawable.ic_menu_search;
    } else {
        clearIcon = android.R.drawable.ic_notification_clear_all;
        searchIcon = 0;
    }
    Drawable leftDrawable =  null;
    if (searchIcon != 0) {
        leftDrawable = getResources().getDrawable(searchIcon);
    }
    Drawable rightDrawable = null;
    if (clearIcon != 0) {
        rightDrawable = getResources().getDrawable(clearIcon);
    }

    mSearchEditText.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, rightDrawable, null);
}


@Override
public boolean onTouch(View aView, MotionEvent aEvent) {
    if (aEvent.getAction() == MotionEvent.ACTION_UP){
        if (aEvent.getX() > ( mSearchEditText.getWidth() - 
         mSearchEditText.getCompoundPaddingEnd())){
            mSearchEditText.setText("");
        }
    }
    return false;
}

使用以下布局:

<FrameLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="9dp"
    android:padding="5dp">

    <EditText
        android:id="@+id/calc_txt_Prise"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="numberDecimal"  
        android:layout_marginTop="20dp"
        android:textSize="25dp"
        android:textColor="@color/gray"
        android:textStyle="bold"
        android:hint="@string/calc_txt_Prise"
        android:singleLine="true" />

    <Button
        android:id="@+id/calc_clear_txt_Prise"      
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="10dp"
        android:layout_gravity="right|center_vertical"
        android:background="@drawable/delete" />

</FrameLayout>

您还可以使用按钮的id，并在其onClickListener方法上执行您想要的任何操作。
