我想要的是一个选项菜单,用户可以选择在以下菜单之间导航:
现在,我已经使用OnClickListener
创建了我的按钮,并使用GestureOverlayView
创建了手势。然后我选择开始一个新的Activity
,具体取决于使用按下按钮还是执行手势。但是,当我尝试绘制手势时,它不会被拾取。仅识别按钮。以下是我的代码:
public class Menu extends Activity implements OnClickListener, OnGesturePerformedListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//create TextToSpeech
myTTS = new TextToSpeech(this, this);
myTTS.setLanguage(Locale.US);
//create Gestures
mLibrary = GestureLibraries.fromRawResource(this, R.raw.gestures);
if (!mLibrary.load()) {
finish();
}
// Set up click listeners for all the buttons.
View playButton = findViewById(R.id.play_button);
playButton.setOnClickListener(this);
View instructionsButton = findViewById(R.id.instructions_button);
instructionsButton.setOnClickListener(this);
View modeButton = findViewById(R.id.mode_button);
modeButton.setOnClickListener(this);
View statsButton = findViewById(R.id.stats_button);
statsButton.setOnClickListener(this);
View exitButton = findViewById(R.id.exit_button);
exitButton.setOnClickListener(this);
GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
}
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
ArrayList<Prediction> predictions = mLibrary.recognize(gesture);
// We want at least one prediction
if (predictions.size() > 0) {
Prediction prediction = predictions.get(0);
// We want at least some confidence in the result
if (prediction.score > 1.0) {
// Show the gesture
Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show();
//User drew symbol for PLAY
if (prediction.name.equals("Play")) {
myTTS.shutdown();
//connect to game
// User drew symbol for INSTRUCTIONS
} else if (prediction.name.equals("Instructions")) {
myTTS.shutdown();
startActivity(new Intent(this, Instructions.class));
// User drew symbol for MODE
} else if (prediction.name.equals("Mode")){
myTTS.shutdown();
startActivity(new Intent(this, Mode.class));
// User drew symbol to QUIT
} else {
finish();
}
}
}
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.instructions_button:
startActivity(new Intent(this, Instructions.class));
break;
case R.id.mode_button:
startActivity(new Intent(this, Mode.class));
break;
case R.id.exit_button:
finish();
break;
}
}
任何建议都将不胜感激!

如果我理解正确,你想在同一个视图上执行点击动作和手势动作,我不知道如何实现这一点,但是,我们可以在按钮后面有隐形视图来处理手势和按钮像往常一样处理点击事件。
默认计算器应用程序使用此方法在正常模式和高级模式之间切换。
参考, com.android.calculator2.PanelSwitcher - 用于手势事件 com.android.calculator2.EventListener - 用于点击事件
希望它有所帮助。
