android——自定义控件(编辑框)、悬浮窗

一、自定义编辑框

效果图：

主要的代码为：

class EditLayout @JvmOverloads constructor(
    context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : ConstraintLayout(context, attrs, defStyleAttr) {
    private var editTitle: String
    private var editContent: String
    private var editType: Int
    private var isMust: Boolean
    private var tvLabelEdit: TextView
    private var ivMustEdit: ImageView
    private var etEdit: EditText
    private var editable: Boolean
 
    init {
        LayoutInflater.from(context).inflate(R.layout.layout_edit, this)
        tvLabelEdit = findViewById(R.id.tv_label_edit)
        ivMustEdit = findViewById(R.id.iv_must_edit)
        etEdit = findViewById(R.id.et_edit)
 
        val typedArray = context.obtainStyledAttributes(attrs, R.styleable.EditLayout)
        editTitle = typedArray.getString(R.styleable.EditLayout_editTitle) ?: ""
        editContent = typedArray.getString(R.styleable.EditLayout_editContent) ?: ""
        editType = typedArray.getInt(R.styleable.EditLayout_editType, 1)
        editable = typedArray.getBoolean(R.styleable.EditLayout_editable, true)
        isMust = typedArray.getBoolean(R.styleable.EditLayout_isMust, false)
 
        typedArray.recycle();
        applyLabel()
        applyIv()
        applyEdit()
    }
 
    private fun applyLabel() {
        tvLabelEdit.text = editTitle
        etEdit.setText(editContent)
    }
 
    private fun applyIv() {
        ivMustEdit.visibility = if (isMust) View.VISIBLE else View.GONE
    }
 
    private fun applyEdit() {
        etEdit.inputType = when (editType) {
            1 -> InputType.TYPE_CLASS_TEXT
            2 -> InputType.TYPE_CLASS_NUMBER
            else -> InputType.TYPE_CLASS_TEXT
        }
        etEdit.isEnabled = editable
    }
 
    fun getEditText(): EditText {
        return etEdit
    }
 
    fun getInputText(): String {
        return etEdit.text.toString()
    }
 
    fun setInputText(input: String) {
        etEdit.setText(input)
    }
}

使用3个原生控件组合而成，具体的代码可以到这里下载:

二、悬浮窗

主要的代码：

@SuppressLint("ClickableViewAccessibility")
class FloatWindow(private val mContext: Context) : LifecycleService() {
    private var floatRootView: View? = null
    private val mBinding: WindowFloatBinding by lazy {
        DataBindingUtil.inflate(LayoutInflater.from(mContext), R.layout.window_float, null, false)
    }
    private val windowManager: WindowManager by lazy {
        mContext.getSystemService(Context.WINDOW_SERVICE) as WindowManager
    }
    private val layoutParams: WindowManager.LayoutParams by lazy {
        WindowManager.LayoutParams().apply {
            width = WindowManager.LayoutParams.WRAP_CONTENT
            height = WindowManager.LayoutParams.WRAP_CONTENT
            flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL or
                    WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
            gravity = Gravity.END
 
            type = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY
            } else {
                WindowManager.LayoutParams.TYPE_PHONE
            }
        }
    }
    private var mAllDoorListen: () -> Unit = {}
 
    init {
        floatRootView = mBinding.root
        floatRootView?.setOnTouchListener(ItemViewTouchListener(layoutParams, windowManager))
        floatRootView?.setBackgroundColor(Color.TRANSPARENT)
 
        val outMetrics = DisplayMetrics()
        windowManager.defaultDisplay.getMetrics(outMetrics)
 
        layoutParams.format = PixelFormat.TRANSPARENT
        mBinding.tvOpenDoorAll.setOnClickListener {
        }
        mBinding.clLeft.setOnClickListener {
            Log.e("TAG", "缩小")
            indenteOrExpand()
        }
 
    }
 
    /** 缩进或者展开 **/
    private fun indenteOrExpand() {
        mBinding.llContentOperate.let {
            if (it.visibility == View.GONE) {
                it.visibility = View.VISIBLE
                mBinding.ivIndenteExpand.setImageResource(R.mipmap.ic_indentation_float)
            } else {
                it.visibility = View.GONE
                mBinding.ivIndenteExpand.setImageResource(R.mipmap.ic_expand_float)
            }
        }
    }
 
    inner class ItemViewTouchListener(
        private val wl: WindowManager.LayoutParams,
        private val windowManager: WindowManager
    ) : View.OnTouchListener {
        //        private var x = 0
        private var y = 0
        override fun onTouch(view: View, motionEvent: MotionEvent): Boolean {
            Log.e("TAG", "位置改变")
            when (motionEvent.action) {
                MotionEvent.ACTION_DOWN -> {
//                    x = motionEvent.rawX.toInt()
                    y = motionEvent.rawY.toInt()
 
                }
                MotionEvent.ACTION_MOVE -> {
//                    val nowX = motionEvent.rawX.toInt()
                    val nowY = motionEvent.rawY.toInt()
//                    val movedX = nowX - x
                    val movedY = nowY - y
//                    x = nowX
                    y = nowY
                    wl.apply {
//                        x += movedX
                        y += movedY
                    }
                    //更新悬浮球控件位置
                    windowManager.updateViewLayout(view, wl)
                }
                else -> {
 
                }
            }
            return false
        }
    }
 
    /** 悬浮窗显示 */
    fun show() {
        windowManager.addView(floatRootView, layoutParams)
    }
 
    /** 悬浮窗移除 */
    fun remove() {
        floatRootView?.let {
            windowManager.removeViewImmediate(it)
            floatRootView = null
        }
    }
 
    /** 设置全部开启按钮监听 */
    fun setOpenAllListener(mListen: () -> Unit) {
        mAllDoorListen = mListen
    }
}
