在 Android 10 上进行屏幕录制的开发可以使用 MediaProjection API。以下是一些基本步骤:
1. 获取 MediaProjectionManager 实例:
```
MediaProjectionManager mediaProjectionManager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);
```
2. 启动屏幕捕获:
```
Intent captureIntent = mediaProjectionManager.createScreenCaptureIntent();
startActivityForResult(captureIntent, REQUEST_CODE);
```
3. 在 onActivityResult() 方法中获取 MediaProjection 对象:
```
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
MediaProjection mediaProjection = mediaProjectionManager.getMediaProjection(resultCode, data);
// 开始录制
startRecording(mediaProjection);
}
}
```
4. 创建 MediaRecorder 对象并设置参数:
```
MediaRecorder mediaRecorder = new MediaRecorder();
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
mediaRecorder.setVideoEncodingBitRate(512 * 1000);
mediaRecorder.setVideoFrameRate(30);
mediaRecorder.setVideoSize(width, height);
mediaRecorder.setOutputFile(outputFile);
```
5. 创建 VirtualDisplay 对象并将其与 MediaRecorder 对象关联:
```
Surface surface = mediaRecorder.getSurface();
VirtualDisplay virtualDisplay = mediaProjection.createVirtualDisplay("ScreenCapture",
width, height, displayMetrics.densityDpi,
DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR,
surface, null, null);
```
6. 开始录制:
```
mediaRecorder.prepare();
mediaRecorder.start();
```
7. 停止录制:
```
mediaRecorder.stop();
mediaRecorder.release();
mediaProjection.stop();
```
这是一个基本的示例,你可以根据自己的需求进行调整和扩展。
