继承EditText增加了两条自定义属性分别为是否显示搜索与删除按钮;

public class SGEditText extends android.support.v7.widget.AppCompatEditText {
private final static String TAG = "SGEditTextWithDel";
private Drawable imgSearch;
private Drawable imgDele;

/**
 * 显示搜索按钮(默认无)
 */
private boolean isShowSearchView = true;
/**
 * 显示删除*(默认显示)
 */
private boolean isShowDelView = true;

public SGEditTextWithDel(Context context) {
    this(context, null);
}

public SGEditTextWithDel(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

public SGEditTextWithDel(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    TypedArray td = context.getTheme().obtainStyledAttributes(attrs, R.styleable.SGEditTextWithDel, defStyle, 0);
    isShowSearchView = td.getBoolean(R.styleable.SGEditTextWithDel_showSearchIcon, false);
    isShowDelView = td.getBoolean(R.styleable.SGEditTextWithDel_showDelIcon, true);
    td.recycle();
    init(context);
}


private void init(Context context) {
    setGravity(Gravity.CENTER_VERTICAL);
    setFocusableInTouchMode(true);
    setFocusable(true);
    setBackgroundResource(R.drawable.bg_edit_cursor);
    imgDele= context.getResources().getDrawable(R.drawable.delete);
    imgSearch = ContextCompat.getDrawable(context, R.drawable.search);
    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) {
            setDrawable();
        }
    });
    setDrawable();
}

private void setDrawable() {
    if (isShowSearchView && isShowDelView) {
        if (length() < 1)
            setCompoundDrawablesWithIntrinsicBounds(imgSearch, null, null, null);
        else
            setCompoundDrawablesWithIntrinsicBounds(imgSearch, null, imgAble, null);
    } else if (isShowDelView && !isShowSearchView) {
        if (length() < 1)
            setCompoundDrawablesWithIntrinsicBounds(null, null, null, null);
        else
            setCompoundDrawablesWithIntrinsicBounds(null, null, imgAble, null);
    } else if (!isShowSearchView && !isShowDelView) {
        setCompoundDrawablesWithIntrinsicBounds(null, null, null, null);
    }
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (imgAble != null && event.getAction() == MotionEvent.ACTION_UP && isShowDelView) {
        int eventX = (int) event.getRawX();
        int eventY = (int) event.getRawY();
        Log.e(TAG, "eventX = " + eventX + "; eventY = " + eventY);
        Rect rect = new Rect();
        getGlobalVisibleRect(rect);
        rect.left = rect.right - 50;
        if (rect.contains(eventX, eventY))
            setText("");
    }
    return super.onTouchEvent(event);
}

@Override
protected void finalize() throws Throwable {
    super.finalize();
}

}

另外附上attrs.xml的两条自定义属性:

<resources>
<attr name="showSearchIcon" format="boolean" />
<attr name="showDelIcon" format="boolean" />
<declare-styleable name="SGEditText">
    <attr name="showSearchIcon" />
    <attr name="showDelIcon" />
</declare-styleable>
</resources>

以及背景：

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<size android:width="1.5dp" />
<solid android:color="@color/spark_white" />
<stroke
    android:width="@dimen/margin_1"
    android:color="#cfcfcf" />
<corners android:radius="5dp"/>
</shape>

在xml中使用：

 <com.spark.civilexam.weight.SGEditText
        android:layout_width="match_parent"
        android:layout_height="35dp"
        android:maxLength="10"
        alu:showDelIcon="true"
        alu:showSearchIcon="true" />
