Android虛擬搖桿

使用方法

①attr中定義自定義參數

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

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);

}

});
