开发的音乐播放器,同步显示歌词
3星 · 编辑精心推荐
下面是一个基于 OkHttp 的简单示例,演示如何通过蓝牙同步 QQ 音乐歌词的展示与播放的 Android 应用:
1. 首先,在你的安卓项目中添加必要的权限,包括蓝牙权限和网络访问权限。可以在 AndroidManifest.xml 文件中添加以下代码:
```xml
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.INTERNET" />
```
2. 在你的布局文件中添加一个 TextView 用于展示歌词,一个 Button 用于开始同步歌词,一个 Button 用于播放音乐。
3. 在你的代码中,使用以下代码来进行蓝牙操作和网络请求:
```java
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothDevice;
import android.bluetooth.BluetoothSocket;
import android.os.Handler;
import android.os.Message;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.io.IOException;
import java.io.InputStream;
import java.util.UUID;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
public class MainActivity extends AppCompatActivity {
private TextView lyricsTextView;
private Button syncButton;
private Button playButton;
private BluetoothAdapter bluetoothAdapter;
private BluetoothSocket bluetoothSocket;
private InputStream inputStream;
private OkHttpClient client;
private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
private static final String DEVICE_ADDRESS = "蓝牙设备地址";
private static final int MESSAGE_READ = 1;
private Handler handler = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
if (msg.what == MESSAGE_READ) {
byte[] buffer = (byte[]) msg.obj;
String lyrics = new String(buffer);
lyricsTextView.setText(lyrics);
}
return true;
}
});
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lyricsTextView = findViewById(R.id.lyricsTextView);
syncButton = findViewById(R.id.syncButton);
playButton = findViewById(R.id.playButton);
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
client = new OkHttpClient();
syncButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
connectBluetooth();
}
});
playButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// 播放音乐的逻辑
}
});
}
private void connectBluetooth() {
BluetoothDevice device = bluetoothAdapter.getRemoteDevice(DEVICE_ADDRESS);
try {
bluetoothSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
bluetoothSocket.connect();
inputStream = bluetoothSocket.getInputStream();
readLyrics();
} catch (IOException e) {
e.printStackTrace();
}
}
private void readLyrics() {
byte[] buffer = new byte[1024];
int bytes;
while (true) {
try {
bytes = inputStream.read(buffer);
String lyrics = new String(buffer, 0, bytes);
sendLyricsRequest(lyrics);
} catch (IOException e) {
e.printStackTrace();
break;
}
}
}
private void sendLyricsRequest(String lyrics) {
String url = "https://api.example.com/lyrics?text=" + lyrics;
Request request = new Request.Builder()
.url(url)
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
}
@Override
public void onResponse(Call call, Response response) throws IOException {
String responseData = response.body().string();
// 解析返回的数据,并进行相应的操作
}
});
}
}
```
请注意,上述代码仅为示例,可能需要根据你的具体需求进行修改和完善。同时,蓝牙连接和网络请求需要在后台线程中进行,以避免阻塞主线程。你还需要处理错误、断开蓝牙连接的情况,并根据具体的 API 和音乐播放库来实现歌词的同步和音乐的播放。
另外,需要在 `DEVICE_ADDRESS` 常量中填入你要连接的蓝牙设备的地址,并根据实际情况修改网络请求的 URL。
