问
Android意图总是崩溃
pomngjkldjg_849_788 发布于 2023-02-12 05:52我正在尝试使用intent切换android中的活动.然而,不管我做什么,这总是崩溃.我在同一个问题上阅读了无数的主题,其中没有一个有帮助.所以我被迫提出自己的问题.
当我运行这个时,应用程序只是在4秒钟后崩溃
这是我的第一个活动(Splash):
package com.redflamedeveloper.torch;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
public class Splash extends Activity {
/** Called when the activity is first created. */
MediaPlayer mpSplash;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
mpSplash = MediaPlayer.create(this, R.raw.fire); //Splash Screen sound
mpSplash.start();
Thread logoTimer = new Thread(){ //4 Second Timer
public void run() {
try {
//Waits for 4 seconds
int logoTimer = 0;
while(logoTimer <4000){
sleep(100);
logoTimer = logoTimer + 100;
}
Intent intentMain = new Intent(Splash.this, Main.class);
startActivity(intentMain);
}
catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally {
finish();
}
}
};
logoTimer.start(); //Starts the thread logoTimer
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mpSplash.release(); //ends sound
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
mpSplash.pause(); //pauses sound
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
mpSplash.start(); //Resumes sound
}
}
我的第二项活动(主要):
package com.redflamedeveloper.torch;
import android.app.Activity;
import android.hardware.Camera.Parameters;
import android.hardware.Camera;
import android.os.Bundle;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.os.Handler;
/**

break;
case R.id.bMorse:
