Android自定义滑动接听电话控件组实例_Android

本文根据组件开发思想，首先介绍android自定义控件，然后将自定义的控件封装为jar包。最为实现滑动接听电话控件组。

一、目录结构

二、运行效果

三、代码实现

首先，自定义一个类IncomingPhone继承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);
  }

构造函数中添加子控件，并添加滑动事件以及监听器，其中PickUpView、HangUpView是自定义的子控件，是该类的内部类两个几乎一样，我贴出其中一个

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("起始坐标", String.valueOf(firstX));
//        Log.e("结束坐标", 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文件中定义

<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="挂断"/>
  </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("", "打电话");
      incomingPhone.setVisibility(View.GONE);
      mBtnHangUp.setVisibility(View.VISIBLE);
    }
    else {
      Log.e("","挂电话");
      incomingPhone.setVisibility(View.GONE);
      mBtnHangUp.setVisibility(View.VISIBLE);
    }
  }
});

问题：图片大小以及屏幕适配可能会有些问题，如果使用，请注意测试。以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
