Android 删除参数以匹配 "intent()"

Question

我正在尝试开始第二个 Activity ，但我收到代码错误。

import android.os.Bundle;
import android.content.Intent;
import android.app.Activity;
import android.widget.Button;

import android.view.View;

import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewStub;
import android.widget.AdapterView;
import android.widget.ImageButton;
import android.widget.Toast;


public class MainActivity extends Activity
{
    private static final int ID_SPLASH = 1;
    private static final int ID_MAIN = 2;
    private static final int ID_PROFILE = 3;
    private static final int ID_PLAY = 4;
    private static final int ID_HELP = 5;


    @Override

    protected void onCreate(Bundle savedInstanceState)
    {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setContentView(R.layout.main);
        ImageButton menuBtn = (ImageButton)findViewById(R.id.iBtn1);
        //Button example1Btn    = (Button) findViewById(R.id.btn1);
        ActionItem splashItem   = new ActionItem(ID_SPLASH, "Splash", getResources().getDrawable(R.drawable.ic_action_about));
        ActionItem mainItem     = new ActionItem(ID_MAIN, "Main", getResources().getDrawable(R.drawable.ic_content_undo));
        ActionItem profileItem  = new ActionItem(ID_PROFILE, "Profile", getResources().getDrawable(R.drawable.ic_social_person));
        ActionItem playItem     = new ActionItem(ID_PLAY, "Play", getResources().getDrawable(R.drawable.ic_hardware_gamepad));
        ActionItem helpItem     = new ActionItem(ID_HELP, "Help", getResources().getDrawable(R.drawable.ic_action_help));

        //use setSticky(true) to disable QuickAction dialog being dismissed after an item is clicked
        helpItem.setSticky(true);

        final QuickAction mQuickAction  = new QuickAction(this);

        mQuickAction.addActionItem(splashItem);
        mQuickAction.addActionItem(mainItem);
        mQuickAction.addActionItem(profileItem);
        mQuickAction.addActionItem(playItem);
        mQuickAction.addActionItem(helpItem);

        //setup the action item click listener
        mQuickAction.setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() {
            @Override
            public void onItemClick(QuickAction quickAction, int pos, int actionId) {
                ActionItem actionItem = quickAction.getActionItem(pos);

                if (actionId == ID_SPLASH) {
                    Intent intent = new Intent(this, SplashActivity.class);
                    startActivity(intent);

                } else if (actionId == ID_MAIN) {
                    Toast.makeText(getApplicationContext(), "Main---> item selected", Toast.LENGTH_SHORT).show();
                } else if (actionId == ID_PROFILE) {
                    Toast.makeText(getApplicationContext(), "Profile---> item selected", Toast.LENGTH_SHORT).show();
                } else if (actionId == ID_PLAY) {
                    Toast.makeText(getApplicationContext(), "Play---> item selected", Toast.LENGTH_SHORT).show();
                } else if (actionId == ID_HELP) {
                    Toast.makeText(getApplicationContext(), "Help---> item selected", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getApplicationContext(), actionItem.getTitle() + " selected", Toast.LENGTH_SHORT).show();
                }
            }
        });

        mQuickAction.setOnDismissListener(new QuickAction.OnDismissListener() {
            @Override
            public void onDismiss() {
                Toast.makeText(getApplicationContext(), "Ups..dismissed", Toast.LENGTH_SHORT).show();
            }
        });

        menuBtn.setOnClickListener(new View.OnClickListener() {         
            @Override
            public void onClick(View v) {
                mQuickAction.show(v);
            }
        });

    }
}

它不喜欢从新开始的一切。

我觉得我遵循了指示 http://developer.android.com/training/basics/firstapp/starting-activity.html

您尝试作为上下文传递的内容实际上是 onActionItemClickListener()，它不会起作用。

应该使用 getBaseContext()。

Intent intent = new Intent(getBaseContext(), SplashActivity.class);

编辑:或者你可以做

Intent intent = new Intent(MainActivity.this, SplashActivity.class);
