Android自定義滑動接聽電話控件組

一、目錄結構

二、運行效果

三、代碼實現

   首先，自定義一個類IncomingPhone繼承RelativeLayout

 public IncomingPhone(Context context, AttributeSet attrs) {
        super(context, attrs);
        mContext = context;
        TextView textView = new TextView(mContext);
        textView.setText("caonima");
        pickUpView = new PickUpView(mContext);
        hangUpView = new HangUpView(mContext);
        pickUpView.setBackground(getResources().getDrawable(R.drawable.pick_up_background));
        hangUpView.setBackground(getResources().getDrawable(R.drawable.hang_up_background));
        RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        lp1.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
//        pickUpView.setBackground(mContext.getDrawable(R.drawable.pick_up_background));
        pickUpView.setPickUpListener(new PickUpView.PickUpListener() {
            @Override
            public void pickUpEvent() {
                mIncomingPhoneResultListener.incomingPhoneResultEvent("PICKUP");
            }
        });
        hangUpView.setHangUpListener(new HangUpView.HangUpListener() {
            @Override
            public void hangUpEvent() {

                mIncomingPhoneResultListener.incomingPhoneResultEvent("HANGUP");
            }
        });
        pickUpView.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                    case MotionEvent.ACTION_DOWN:
                        hangUpView.setVisibility(View.GONE);
                        break;
                    case MotionEvent.ACTION_UP:
                        hangUpView.setVisibility(View.VISIBLE);
                        pickUpView.setVisibility(View.VISIBLE);
                        break;
                    default:
                        break;
                }
                return false;
            }
        });
        hangUpView.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                    case MotionEvent.ACTION_DOWN:
                        pickUpView.setVisibility(View.GONE);
                        break;
                    case MotionEvent.ACTION_UP:
                        hangUpView.setVisibility(View.VISIBLE);
                        pickUpView.setVisibility(View.VISIBLE);
                        break;
                    default:
                        break;
                }
                return false;
            }
        });
        addView(textView);
        addView(pickUpView);
        addView(hangUpView,lp1);
    }

構造函數中添加子控件，並添加滑動事件以及監聽器，其中PickUpView、HangUpView是自定義的子控件，是該類的內部類兩個幾乎一樣，我貼出其中一個

class PickUpView extends RelativeLayout {
    private Context mContext;
    private final int minWidth = 360;
    private int screenWidth;
    private int mWidth;
    private int mHeight;
    private PickUpListener mPickUpListener;

    public void setPickUpListener(PickUpListener mPickUpListener) {
        this.mPickUpListener = mPickUpListener;
    }

    public int getmWidth() {
        mWidth = getLayoutParams().width;
        return mWidth;
    }

    public void setmWidth(int width) {
        mWidth = width;
        getLayoutParams().width = mWidth;
        requestLayout();
    }

    public int getmHeight() {
        mHeight = getLayoutParams().height;
        return mHeight;
    }

    public void setmHeight(int height) {
        mHeight = height;
        getLayoutParams().height = mHeight;
        requestLayout();
    }
    public PickUpView(Context context) {

        super(context);
        WindowManager wm = (WindowManager) getContext()
                .getSystemService(Context.WINDOW_SERVICE);

        screenWidth = wm.getDefaultDisplay().getWidth();
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        int firstX = 0;
        int lastX = 0;
        mWidth = getmWidth();
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                firstX = (int) event.getX();
//                ObjectAnimator.ofInt(this,"mWidth",500).setDuration(5000).start();
                break;
            case MotionEvent.ACTION_MOVE:
                lastX = (int) event.getX();
                setmWidth(lastX);
//                Log.e("起始座標", String.valueOf(firstX));
//                Log.e("結束座標", String.valueOf(lastX));
                break;
            case MotionEvent.ACTION_UP:
                lastX = (int) event.getRawX();
                if (lastX > screenWidth / 7 * 6) {
                    mPickUpListener.pickUpEvent();
                } else {
                    setmWidth(minWidth);
                }
                break;
            default:
                break;
        }
        return true;
    }

    public interface PickUpListener {
        public void pickUpEvent();
    }
}

在XML文件中定義

 <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <com.example.administrator.pickuptest.IncomingPhone
            android:id="@+id/incoming"
            android:layout_width="match_parent"
            android:layout_height="80dp">
        </com.example.administrator.pickuptest.IncomingPhone>
        <Button
            android:id="@+id/btn_hang_up"
            android:layout_margin="10dp"
            android:background="#ff0000"
            android:textColor="#ffffff"
            android:visibility="gone"
            android:layout_width="match_parent"
            android:layout_height="80dp"
            android:text="掛斷"/>
    </RelativeLayout>

在Activity中使用

        incomingPhone = (IncomingPhone)findViewById(R.id.incoming);
        mBtnHangUp=(Button)findViewById(R.id.btn_hang_up);
        incomingPhone.setIncomingPhoneResultListener(new IncomingPhone.IncomingPhoneResultListener() {
            @Override
            public void incomingPhoneResultEvent(String result) {
                if ("PICKUP".equals(result)){
                    Log.e("", "打電話");
                    incomingPhone.setVisibility(View.GONE);
                    mBtnHangUp.setVisibility(View.VISIBLE);
                }
                else {
                    Log.e("","掛電話");
                    incomingPhone.setVisibility(View.GONE);
                    mBtnHangUp.setVisibility(View.VISIBLE);
                }
            }
        });

問題：圖片大小以及屏幕適配可能會有些問題，如果使用，請注意測試
