示例1: onGenericMotion
import android.view.InputDevice.MotionRange; //导入依赖的package包/类
@Override
public boolean onGenericMotion(View v, MotionEvent event) {
if ((event.getSource() & InputDevice.SOURCE_CLASS_JOYSTICK) != 0
&& event.getAction() == MotionEvent.ACTION_MOVE) {
List<MotionRange> motionRanges = event.getDevice().getMotionRanges();
for(MotionRange mr : motionRanges){
int axis = mr.getAxis();
if(event.getAxisValue(axis) > 0.5 || event.getAxisValue(axis) < -0.5){
Log.i(TAG, "Axis found: " + MotionEvent.axisToString(axis));
this.mAxisName = MotionEvent.axisToString(axis);
mValueTextView.setText(mAxisName);
}
}
}else{
Log.i(TAG, "Not a joystick event.");
}
return true;
}
示例2: getAxisValue
import android.view.InputDevice.MotionRange; //导入依赖的package包/类
private float getAxisValue(MotionEvent motionEvent, int axis) {
InputDevice device = InputDevice.getDevice(mDeviceId);
if (device == null) {
return 0f;
}
MotionRange range = device.getMotionRange(axis, motionEvent.getSource());

}
final float flat = range.getFlat();
final float value = motionEvent.getAxisValue(axis);
if (Math.abs(value) > flat) {
return value;
}
return 0f;
}
示例3: processAxis
import android.view.InputDevice.MotionRange; //导入依赖的package包/类
/**
* Normalizes joystick values between -1.0 and 1.0. Though Android guarantees
* this, it is a useful function if one finds that the joystick values are not
* correct. Doesn't do any harm to call it.
*/
public static float processAxis(InputDevice.MotionRange range, float axisvalue)
/*************************************************************************/

float absAxisValue = Math.abs(axisvalue);
float deadZone = range.getFlat();
if (absAxisValue <= deadZone)
{
return 0.0f;
}

if (axisvalue < 0.0f)
{
normalizedValue = absAxisValue / range.getMin();
}
else
{
