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:

明确的文本:

"文本字段带有清晰的文本尾随图标。"

如果设置了，当文本出现时将显示一个图标，按下该图标将清除输入文本。

    ...
    app:endIconMode="clear_text">
​
    ...
​
</com.google.android.material.textfield.TextInputLayout>

我把它留在这里:

material.io

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;
}

下面是kotlin中简单的完整解决方案。

整个布局就是你的搜索栏

<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="35dp"
        android:layout_margin="10dp"
        android:background="@drawable/your_desired_drawable">

        <EditText
            android:id="@+id/search_et"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentStart="true"
            android:layout_toStartOf="@id/clear_btn"
            android:background="@null"
            android:hint="search..."
            android:imeOptions="actionSearch"
            android:inputType="text"
            android:maxLines="1"
            android:paddingStart="15dp"
            android:paddingEnd="10dp" />

        <ImageView
            android:id="@+id/clear_btn"
            android:layout_width="20dp"
            android:layout_height="match_parent"
            android:layout_alignParentEnd="true"
            android:layout_centerInParent="true"
            android:layout_marginEnd="15dp"
            android:visibility="gone"
            android:src="@drawable/ic_baseline_clear_24"/>

    </RelativeLayout>

现在这是清除按钮的功能，粘贴这段代码在onCreate方法。

search_et.addTextChangedListener(object: TextWatcher {
            override fun beforeTextChanged(s:CharSequence, start:Int, count:Int, after:Int) {
            }
            override fun onTextChanged(s:CharSequence, start:Int, before:Int, count:Int) {
            }
            override fun afterTextChanged(s: Editable) {
                if (s.isNotEmpty()){
                    clear_btn.visibility = VISIBLE
                    clear_btn.setOnClickListener {
                        search_et.text.clear()
                    }
                }else{
                    clear_btn.visibility = GONE
                }
            }
        })

您可以使用这个代码片段和Jaydip回答多个按钮。在获得ET和按钮元素的引用后调用它。我使用了vececotr button，所以你必须将button元素更改为ImageButton:

private void setRemovableET(final EditText et, final ImageButton resetIB) {

        et.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus && et.getText().toString().length() > 0)
                    resetIB.setVisibility(View.VISIBLE);
                else
                    resetIB.setVisibility(View.INVISIBLE);
            }
        });

        resetIB.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                et.setText("");
                resetIB.setVisibility(View.INVISIBLE);
            }
        });

        et.addTextChangedListener(new TextWatcher() {
            @Override
            public void afterTextChanged(Editable s) {}
            @Override
            public void beforeTextChanged(CharSequence s, int start,
                                          int count, int after) {
            }
            @Override
            public void onTextChanged(CharSequence s, int start,
                                      int before, int count) {
                if(s.length() != 0){
                    resetIB.setVisibility(View.VISIBLE);
                }else{
                    resetIB.setVisibility(View.INVISIBLE);
                }
            }
        });
    }

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:
