#Android虚拟摇杆
##使用方法
##①attr中定义自定义参数
<!-- areaBackground 设置区域背景
rockerBackground 设置摇杆的样式
rockerScale 设置摇杆的相对于背景的比例
rockerSpeedLevel 设置当前位置相对于中心点的距离的比例 如：10 则中心点到边缘的距离分为10分 越靠外数值越大0-10
rockerCallBackMode 有变化就回调，或者是方向改变才会回调-->
<declare-styleable name="RockerView">
<attr name="areaBackground" format="color|reference" />
<attr name="rockerBackground" format="color|reference" />
<attr name="rockerScale" format="float"/>
<attr name="rockerSpeedLevel" format="integer" />
<attr name="rockerCallBackMode">
<flag name="CALL_BACK_MODE_MOVE" value="0" />
<flag name="CALL_BACK_MODE_STATE_CHANGE" value="1" />
</attr>
</declare-styleable>
##②复制RockerView到项目中
##③使用摇杆控件
<org.jinkia.jk_rockerview.RockerView
android:id="@+id/my_rocker"
android:layout_width="200dp"
android:layout_height="200sp"
android:background="@color/colorPrimary"
app:areaBackground="@mipmap/rocker_base"
app:rockerBackground="@mipmap/rocker"
app:rockerSpeedLevel="10"
app:rockerCallBackMode="CALL_BACK_MODE_STATE_CHANGE"
app:rockerScale="0.5" />
###③事件回调
mRockerView.setOnShakeListener(DIRECTION_8, new RockerView.OnShakeListener() {
@Override
public void onStart() {
}
@Override
public void direction(RockerView.Direction direction) {
if (direction == RockerView.Direction.DIRECTION_CENTER){
mTvShake.setText("当前方向：中心");
}else if (direction == RockerView.Direction.DIRECTION_DOWN){
mTvShake.setText("当前方向：下");
}else if (direction == RockerView.Direction.DIRECTION_LEFT){
mTvShake.setText("当前方向：左");
}else if (direction == RockerView.Direction.DIRECTION_UP){
mTvShake.setText("当前方向：上");
}else if (direction == RockerView.Direction.DIRECTION_RIGHT){
mTvShake.setText("当前方向：右");
}else if (direction == RockerView.Direction.DIRECTION_DOWN_LEFT){
mTvShake.setText("当前方向：左下");
}else if (direction == RockerView.Direction.DIRECTION_DOWN_RIGHT){
mTvShake.setText("当前方向：右下");
}else if (direction == RockerView.Direction.DIRECTION_UP_LEFT){
mTvShake.setText("当前方向：左上");
}else if (direction == RockerView.Direction.DIRECTION_UP_RIGHT){
mTvShake.setText("当前方向：右上");
}
}
@Override
public void onFinish() {
}
});
mRockerView.setOnAngleChangeListener(new RockerView.OnAngleChangeListener() {
@Override
public void onStart() {
}
@Override
public void angle(double angle) {
mTvAngle.setText("当前角度："+angle);
}
@Override
public void onFinish() {
}
});
mRockerView.setOnDistanceLevelListener(new RockerView.OnDistanceLevelListener() {
@Override
public void onDistanceLevel(int level) {
mTvLevel.setText("当前距离级别："+level);
}
});
