Android 监听 摇杆,Android虚拟摇杆 摇杆 方向控制
Android虛擬搖桿
使用方法
①attr中定義自定義參數(shù)
②復制RockerView到項目中
③使用搖桿控件
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事件回調(diào)
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("當前方向：中心");
}else if (direction == RockerView.Direction.DIRECTION_DOWN){
mTvShake.setText("當前方向：下");
}else if (direction == RockerView.Direction.DIRECTION_LEFT){
mTvShake.setText("當前方向：左");
}else if (direction == RockerView.Direction.DIRECTION_UP){
mTvShake.setText("當前方向：上");
}else if (direction == RockerView.Direction.DIRECTION_RIGHT){
mTvShake.setText("當前方向：右");
}else if (direction == RockerView.Direction.DIRECTION_DOWN_LEFT){
mTvShake.setText("當前方向：左下");
}else if (direction == RockerView.Direction.DIRECTION_DOWN_RIGHT){
mTvShake.setText("當前方向：右下");
}else if (direction == RockerView.Direction.DIRECTION_UP_LEFT){
mTvShake.setText("當前方向：左上");
}else if (direction == RockerView.Direction.DIRECTION_UP_RIGHT){
mTvShake.setText("當前方向：右上");
}
}
@Override
public void onFinish() {
}
});
mRockerView.setOnAngleChangeListener(new RockerView.OnAngleChangeListener() {
@Override
public void onStart() {
}
@Override
public void angle(double angle) {
mTvAngle.setText("當前角度："+angle);
}
@Override
public void onFinish() {
}
});
mRockerView.setOnDistanceLevelListener(new RockerView.OnDistanceLevelListener() {
@Override
public void onDistanceLevel(int level) {
mTvLevel.setText("當前距離級別："+level);
}
});
