In android there is no default text clear button functionality in EditText so here is a simple example of implementing text clear button in edit-text, You just have to follow instruction given below to make it in your edit-text.

1)- First you have to create a class MyEditText.jave

public class MyEditText extends EditText {
private static final int MAX_LENGTH = 102;

public MyEditText(Context context, AttributeSet attrs) {
    super(context, attrs);

    if (Build.VERSION.SDK&#95;INT < Build.VERSION&#95;CODES.ICE&#95;CREAM&#95;SANDWICH) {
        this.setBackgroundResource(android.R.drawable.edit&#95;text);
    }

    setOnEditorActionListener(new OnEditorActionListener() {
        @Override
        public synchronized boolean onEditorAction(TextView v,
                int actionId, KeyEvent event) {

            return false;
        }
    });

    String value = "";
    final String viewMode = "editing";
    final String viewSide = "right";
    final Drawable x = getResources().getDrawable(R.drawable.cross);

    // The height will be set the same with [X] icon
    //setHeight(x.getBounds().height());

    x.setBounds(0, 0, x.getIntrinsicWidth(), x.getIntrinsicHeight());
    Drawable x2 = viewMode.equals("never") ? null : viewMode
            .equals("always") ? x : viewMode.equals("editing") ? (value
                    .equals("") ? null : x)
                    : viewMode.equals("unlessEditing") ? (value.equals("") ? x
                            : null) : null;
                    // Display search icon in text field




                    setOnTouchListener(new OnTouchListener() {
                        @Override
                        public boolean onTouch(View v, MotionEvent event) {
                            if (getCompoundDrawables()[viewSide.equals("left") ? 0 : 2] == null) {
                                return false;
                            }
                            if (event.getAction() != MotionEvent.ACTION&#95;UP) {
                                return false;
                            }
                            // x pressed
                            if ((viewSide.equals("left") && event.getX() < getPaddingLeft()
                                    + x.getIntrinsicWidth())
                                    || (viewSide.equals("right") && event.getX() > getWidth()
                                            - getPaddingRight() - x.getIntrinsicWidth())) {
                                Drawable x3 = viewMode.equals("never") ? null : viewMode
                                        .equals("always") ? x
                                                : viewMode.equals("editing") ? null : viewMode
                                                        .equals("unlessEditing") ? x : null;
                                setText("");
                                setCompoundDrawables(null, null,
                                        viewSide.equals("right") ? x3 : null, null);
                            }
                            return false;
                        }
                    });
                    addTextChangedListener(new TextWatcher() {
                        @Override
                        public void onTextChanged(CharSequence s, int start, int before,
                                int count) {
                            Drawable x4 = viewMode.equals("never") ? null : viewMode
                                    .equals("always") ? x
                                            : viewMode.equals("editing") ? (getText().toString()
                                                    .equals("") ? null : x) : viewMode
                                                    .equals("unlessEditing") ? (getText()
                                                            .toString().equals("") ? x : null) : null;
                                                    setCompoundDrawables(null, null,
                                                            viewSide.equals("right") ? x4 : null, null);
                        }

                        @Override
                        public void afterTextChanged(Editable s) {
                            if (s != null && s.length() > MAX&#95;LENGTH) {
                                setText(s.subSequence(0, MAX&#95;LENGTH));
                                setSelection(MAX&#95;LENGTH);
                            }
                        }

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

2)- Call this class in your activity like this.

MyEditText  searchEditText=(MyEditText)findViewById(R.id.search_edittext);

3)- Now you just have to make changes in your .xml file in your project.

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout&#95;width="match&#95;parent"
android:layout&#95;height="match&#95;parent"
tools:ignore="MergeRootFrame" >

<com.receiptbook.android.utility.MyEditText
    android:id="@+id/search&#95;edittext"
    android:layout&#95;width="fill&#95;parent"
    android:layout&#95;height="50dip"
    android:layout&#95;marginTop="15dip"
    android:drawableLeft="@drawable/icon&#95;search"
    android:inputType="textCapWords"
    android:padding="15dip"
    android:singleLine="true" />



 </RelativeLayout>

Thats it hope you like it..:)
