Question

我正在开发一个Android应用程序，而不是加载下一个活动的启动画面，继续发布吐司并进入无限循环！我在这里发布了所需的代码和logcat：

SplashScreen.java：

  package com.example.ambuj.supercabs;

  import android.content.Intent;
  import android.support.v7.app.ActionBarActivity;
  import android.os.Bundle;
  import android.view.Menu;
  import android.view.MenuItem;
  import android.os.Handler;
  import android.app.Activity;


  public class SplashScreen extends ActionBarActivity {

  private final int SPLASH_DISPLAY_TIMER = 5000;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_screen);

    Thread loading = new Thread() {
        public void run() {
            try {
                sleep(2000);
                Intent main = new Intent(SplashScreen.this,loginActivity.class);
                startActivity(main);
                finish();


            }

            catch (Exception e) {
                e.printStackTrace();
            }

            finally {
                SplashScreen.this.finish();
            }
        }
    };

    loading.start();
}


   /**new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            Intent mainIntent = new Intent(SplashScreen.this,loginActivity.class);
            SplashScreen.this.startActivity(mainIntent);
            SplashScreen.this.finish();
        }
    },SPLASH_DISPLAY_TIMER);   }*/


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_splash_screen, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}
}

这是loginActivity.java：

package com.example.ambuj.supercabs;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
import android .content.Context;


public class loginActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = getIntent();
    Context context = getApplicationContext();
    CharSequence text = "Please fill your login details!";
    int duration = Toast.LENGTH_SHORT;

    Toast toast = Toast.makeText(context, text, duration);
    toast.show();
    toast.setGravity(Gravity.BOTTOM,0,0);
    loginActivity.this.startActivity(intent);
    loginActivity.this.finish();
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_login, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

}

这是我的logcat：

Answer 1

如何处理Splash是

private static int SPLASH_TIME_OUT = 2000;//declare it as class level

然后在你的onCreate

new Handler().postDelayed(new Runnable() {

            /*
             * Showing splash screen with a timer. This will be useful when you
             * want to show case your app logo / company
             */

            @Override
            public void run() {
                // This method will be executed once the
                // timer is over
                // Start your app main activity
                Intent i = new Intent(SplashScreen0.this, SplashScreen1.class);
                startActivity(i);

                // close this activity
                finish();
            }
        }, SPLASH_TIME_OUT);

Answer 2

   package com.example.ambuj.supercabs;

import android.content.Intent;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.os.Handler;
import android.app.Activity;


public class SplashScreen extends Activity {




@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);

Thread loading = new Thread() {
    public void run() {
        try {
            sleep(2000);
            Intent main = new Intent(SplashScreen.this,loginActivity.class);
            startActivity(main);
            finish();


        }

        catch (Exception e) {
            e.printStackTrace();
        }

    }
};

loading.start();
}
}

Splash Screen成无限循环
