在Android Studio中裁剪Mapbox中的语音指令,您可以按照以下步骤进行操作:
以下是示例代码:
import com.mapbox.api.directions.v5.models.VoiceInstructions;
import com.mapbox.services.android.navigation.v5.navigation.NavigationRoute;
import com.mapbox.api.navigation.v1.navigation.NavigationRoute;
public class MainActivity extends AppCompatActivity {
private MapboxMap mapboxMap;
private MapView mapView;
private SpeechAPIClient speechAPIClient;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Mapbox.getInstance(this, "YOUR_MAPBOX_ACCESS_TOKEN");
setContentView(R.layout.activity_main);
mapView = findViewById(R.id.mapView);
mapView.onCreate(savedInstanceState);
mapView.getMapAsync(new OnMapReadyCallback() {
@Override
public void onMapReady(@NonNull MapboxMap mapboxMap) {
MainActivity.this.mapboxMap = mapboxMap;
// 初始化语音指令API客户端
speechAPIClient = MapboxSpeechAPIClient.fromMapboxAccessToken("YOUR_MAPBOX_ACCESS_TOKEN");
// 调用导航路线API获取导航数据
NavigationRoute.builder(MainActivity.this)
.accessToken("YOUR_MAPBOX_ACCESS_TOKEN")
.origin(Point.fromLngLat(-122.42, 37.78))
.destination(Point.fromLngLat(-77.03, 38.91))
.build()
.getRoute(new Callback<DirectionsResponse>() {
@Override
public void onResponse(Call<DirectionsResponse> call, Response<DirectionsResponse> response) {
DirectionsRoute route = response.body().routes().get(0);
// 获取语音指令数据
List<VoiceInstructions> voiceInstructions = route.voiceInstructions();
// 裁剪语音指令
String croppedVoiceInstruction = voiceInstructions.get(0).announcement().substring(0, 10);
// 播放语音指令
playVoiceInstruction(croppedVoiceInstruction);
}
@Override
public void onFailure(Call<DirectionsResponse> call, Throwable throwable) {
// 处理导航路线请求失败的情况
}
});
}
});
}
private void playVoiceInstruction(String voiceInstruction) {
// 使用MediaPlayer或其他库播放语音指令
// TODO: Implement voice instruction playback
}
@Override
protected void onStart() {
super.onStart();
mapView.onStart();
}
@Override
protected void onResume() {
super.onResume();
mapView.onResume();
}
@Override
protected void onPause() {
super.onPause();
mapView.onPause();
}
@Override
protected void onStop() {
super.onStop();
mapView.onStop();
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mapView.onSaveInstanceState(outState);
}
@Override
public void onLowMemory() {
super.onLowMemory();
mapView.onLowMemory();
}
@Override
protected void onDestroy() {
super.onDestroy();
mapView.onDestroy();
}
}
请注意,上述代码只是一个示例,您需要根据自己的具体需求和项目来进行相应的修改。另外,您还可以参考Mapbox的官方文档来获取更详细的信息和教程:Mapbox开发者文档。
