我遇到了视频观看的问题，问题是＆＃34; videoescolhido.setVideoURI（videoplay）;＆＃34;，＆＃39;因为Log我可以检查是否有URI在变量（texto3）中，每次都有，但无法创建mediaPlayer，
这是我的启动码：
public class TelaHome extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
butvideo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
launchMainActivity();
}
});
}
@Override
public void onResume(){
super.onResume();
if (pacotemain != null) {
nomedovideo = pacotemain.getString("arquivo");
urivideo = pacotemain.getString("curPF");
String formato = "";
String mp4 = "mp4"; String avi = "avi"; String wmv = "wmv"; String gpp = "3gp";
char[] lala;
if (nomedovideo != null) {
lala = (nomedovideo.toCharArray());
int x = nomedovideo.length();
for (int i = x - 3; i < x; i++) {
formato = (formato + lala[i]);
}
Log.i(TAG,"Tipo do formato=" + formato);
if (mp4.equalsIgnoreCase(formato) || wmv.equalsIgnoreCase(formato) || avi.equalsIgnoreCase(formato) || gpp.equalsIgnoreCase(formato)){
textovideo.setText(nomedovideo);
cont++;
videocheck.setImageResource(R.mipmap.ic_checked);
simvid = true;
}
else{
textovideo.setText(nomedovideo);
cont=0;
videocheck.setImageResource(R.mipmap.ic_not_checked);
simvid = false;
Toast.makeText(TelaHome.this,
"Video selecionado não aceito!", Toast.LENGTH_SHORT).show();
}
Log.i(TAG,"Valor do cont="+ String.valueOf(cont));
}
}
if (letra != null){
legcheck.setImageResource(R.mipmap.ic_checked);
simleg = true;
}
else{
legcheck.setImageResource(R.mipmap.ic_not_checked);
simleg = false;
}
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
abrirplay(simvid,simleg, pacotemain, letra);
}
}, 1500);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == Activity.RESULT_OK){
videointent = data;
pacotemain = videointent.getExtras();
}
}
if (requestCode == 7) {
if(resultCode == Activity.RESULT_OK){
letraintent = data;
letra = letraintent.getExtras();
}
}
}//onActivityResult
private void launchMainActivity() {
simvid = false;
Intent video = new Intent(this, MainActivity.class);
num = 1;
Bundle bundle = new Bundle();
bundle.putInt("numero", num);
video.putExtras(bundle);
startActivityForResult(video, 1);
}
public void clickButLeg(View view){
tentar();
}
private void tentar (){
simleg = false;
Intent legenda = new Intent(TelaHome.this, AreaLegenda.class);
startActivityForResult(legenda,7);
}
private void abrirplay(Boolean yeap, Boolean legap, final Bundle videolocal, final Bundle letra){
if (yeap == true && legap == true){
butstart.setVisibility(View.VISIBLE);
butstart.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent ultima = new Intent(TelaHome.this, TelaPlay.class);
ultima.putExtra("video",videolocal);
ultima.putExtra("letra",letra);
startActivity(ultima);
}
});
}
}
@Override
public void onDestroy(){
super.onDestroy();
finish();
}
}
这里是视频观看的地方。
public class TelaPlay extends Activity {
TextView letraatual;
TextView letraapos;
public VideoView videoescolhido;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tela_play);
Intent chegou = getIntent();
String texto3 = chegou.getExtras().getBundle("video").getString("curPF");
letraatual = findViewById(R.id.letraatual);
letraapos = findViewById(R.id.letraapos);
videoescolhido = findViewById(R.id.videoView2);
Log.i(TAG,texto3);
letraapos.setText(texto3);
try {
// Start the MediaController
MediaController mediaController = new MediaController(TelaPlay.this);
mediaController.setAnchorView(videoescolhido);
//URI para o video
Uri videoplay = Uri.parse(texto3);
videoescolhido.setMediaController(mediaController);
videoescolhido.setVideoURI(videoplay);
}
catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
videoescolhido.requestFocus();
videoescolhido.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
videoescolhido.start();
}
});
}
}
问题是当＆＃34; videoescolhido.setVideoURI（videoplay）;＆＃34;，＆＃39;因为Log我可以检查变量（texto3）中是否有URI，并且每次都有，但无法创建mediaPlayer，
这是错误：
