我知道人们对此发表了帖子,但我仍然对如何将它应用于我的应用感到困惑。这是我的代码希望你们能解决这个问题
MainActivity Code:
package an.lynxstore;
import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.net.Uri;
import an.lynxstore.a.ATE;
import an.lynxstore.base.BaseThemedActivity;
import an.lynxstore.dialogs.AboutDialog;
public class MainActivity extends BaseThemedActivity implements NavigationView.OnNavigationItemSelectedListener {
Intent myIntent = new Intent(MainActivity.this, LynxMusic.class);
startActivity(myIntent);
private DrawerLayout mDrawer;
@SuppressWarnings("ConstantConditions")
@Override
protected void onCreate(Bundle savedInstanceState) {
if (!ATE.config(this, "light_theme").isConfigured(4)) {
ATE.config(this, "light_theme")
.activityTheme(R.style.AppTheme)
.primaryColorRes(R.color.colorPrimaryLightDefault)
.accentColorRes(R.color.colorAccentLightDefault)
.coloredNavigationBar(false)
.navigationViewSelectedIconRes(R.color.colorAccentLightDefault)
.navigationViewSelectedTextRes(R.color.colorAccentLightDefault)
.commit();
}
if (!ATE.config(this, "dark_theme").isConfigured(4)) {
ATE.config(this, "dark_theme")
.activityTheme(R.style.AppThemeDark)
.primaryColorRes(R.color.colorPrimaryDarkDefault)
.accentColorRes(R.color.colorAccentDarkDefault)
.coloredNavigationBar(true)
.navigationViewSelectedIconRes(R.color.colorAccentDarkDefault)
.navigationViewSelectedTextRes(R.color.colorAccentDarkDefault)
.commit();
}
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Toolbar toolbar = (Toolbar) findViewById(R.id.appbar_toolbar);
setSupportActionBar(toolbar);
toolbar.setTitle(R.string.app_name);
toolbar.setNavigationIcon(R.drawable.ic_menu);
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawer.setDrawerListener(new ActionBarDrawerToggle(this, mDrawer, toolbar, R.string.drawer_open, R.string.drawer_close));
final NavigationView navView = (NavigationView) findViewById(R.id.navigation_view);
navView.setNavigationItemSelectedListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onNavigationItemSelected(MenuItem item) {
mDrawer.closeDrawers();
final int mItemId = item.getItemId();
mDrawer.postDelayed(new Runnable() {
@Override
public void run() {
switch (mItemId) {
case R.id.drawer_settings:
startActivity(new Intent(MainActivity.this, SettingsActivity.class));
break;
case R.id.drawer_about:
AboutDialog.show(MainActivity.this);
break;
}
}
}, 75);
return true;
}
LynxMusic代码:
package an.lynxstore;
import android.media.MediaPlayer;
import android.os.AsyncTask;
public class LynxMusic extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... params) {
MediaPlayer player = MediaPlayer.create(myIntent.this, R.raw.lynx);
player.setLooping(true); // Set looping
player.setVolume(100,100);
player.start();
return null;
}
}
再次感谢您的帮助!我是新手。

为了在用户与其进行交互时在应用程序位置的后台播放媒体,您必须从应用程序的主要活动启动服务,该服务应包含与播放相关的所有方法。要允许活动与服务交互,还需要服务连接。简而言之,我们需要实现有界服务。
