使用方法：

//在.xml文件中
<com.example.gaodemap.TextViewDrawableClick
        android:id="@+id/history_name"

        android:layout_height="48dp"

        android:drawableRight="@drawable/history_delete"
        android:textSize="56px"
        android:gravity="center"
        android:drawablePadding="8dp"
        android:clickable="true"/>//这一句非常重要，TextView默认不可点击

TextViewDrawableClick historyName = findViewById(R.id.history_name);
historyName.setText("我是文字");
historyName.setOnTextClickListener(new TextViewDrawableClick.OnTextClickListener() {
                @Override
