android:仿微信錄製短視頻的實現
一、需求
仿微信短視頻錄製，點擊拍照，長按錄視頻
二、實現代碼
1、RecordVideoActivity
/**

* 錄製視頻的界面
*/
public class RecordVideoActivity extends TitleActivity {
private JCameraView mJCameraView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);//沒有標題
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);//設置全屏
this.getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);//設置豎屏
setContentView(R.layout.record_video);
mJCameraView = (JCameraView) findViewById(R.id.cameraView);
mJCameraView.setActivity(this);
//設置視頻保存路徑（如果不設置默認爲Environment.getExternalStorageDirectory().getPath()）
mJCameraView.setAutoFocus(false);// mJCameraView.setSaveVideoPath(Environment.getExternalStorageDirectory().getPath());
mJCameraView.setCameraViewListener(new JCameraView.CameraViewListener() {
@Override
public void quit() {

}
@Override
public void captureSuccess(Bitmap bitmap) {//拍照成功
String url = FileUtil.saveBitmapToSDCard(bitmap);//拍照保存路徑
Intent intent = new Intent();
//把返回數據存入Intent 0是照片,1是視頻
intent.putExtra("url", url);
intent.putExtra("type", 0);
//設置返回數據
setResult(RESULT_OK, intent);
finish();
}
@Override
public void recordSuccess(String url) {//錄視頻成功
Intent intent = new Intent();

}
});
}
@Override

builder.setTitle("提示")
.setMessage("沒有照相機權限,請賦予本權限再開始拍照吧~").setPositiveButton("確定", new DialogInterface.OnClickListener() {

}
}).show();

};}
2、record_video.xml
