Question

您好我对Android开发相当新，并且通常似乎理解这一点，我一直在关注youtube的教程，它一切正常，直到现在我一直收到应用程序意外停止的错误消息。< / p>

现在我有两个Java文件：

Game.java
MainMenu.java

我有四个XML文件：

activity_game.xml
activity_main_menu.xml
pause_menu.xml
pause.xml

以下是Game.java的代码：

package com.example.deepseadiver;

import android.support.v7.app.ActionBarActivity;
import android.annotation.TargetApi;
import android.os.Build;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.widget.RelativeLayout;

public class Game extends ActionBarActivity {

    View Pause;
    View Pause_Menu;
    RelativeLayout Rel_main_game;

    //Option for user selecting continue
    OnClickListener Continue_List = new OnClickListener() {

        @Override
        public void onClick(View v) {
            //Make the pause menu invisible
            Pause_Menu.setVisibility(View.GONE);
            //Make the game Visible
            Pause.setVisibility(View.VISIBLE);

        }
    };

    //Option for user selecting Main Menu
    OnClickListener Main_Menu_List = new OnClickListener() {

        @Override
        public void onClick(View v) {
            Game.this.finish();

        }
    };


    OnClickListener Pause_Click = new OnClickListener() {

        @Override
        public void onClick(View v) {
            Pause.setVisibility(View.GONE);
            Pause_Menu.setVisibility(View.VISIBLE);
        }
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_game);
        Rel_main_game = (RelativeLayout) findViewById(R.id.Game_Screen);

        //Gets the size of the device Screen
        DisplayMetrics Size = new DisplayMetrics();
        this.getWindowManager().getDefaultDisplay().getMetrics(Size);

        @SuppressWarnings("unused")
        //Sets the screen Width & Height in pixels
        final int Screen_Height = Size.heightPixels;
        final int Screen_Width = Size.widthPixels;

        //Sets the Pause button Layout
        @SuppressWarnings("static-access")
        LayoutInflater myInflater = (LayoutInflater) getApplicationContext().getSystemService(getApplicationContext().LAYOUT_INFLATER_SERVICE);
        Pause = myInflater.inflate(R.layout.pause, null, false);
        Pause.setX(Screen_Width - 250);
        Pause.setY(0);
        Rel_main_game.addView(Pause);

        Pause.setOnClickListener(Pause_Click);

        //Sets the Height and Width
        Pause.getLayoutParams().height=250;
        Pause.getLayoutParams().width=250;

        Pause = myInflater.inflate(R.layout.pause_menu, null, false);
        Rel_main_game.addView(Pause_Menu);

        Pause_Menu.setVisibility(View.GONE);

        ImageView Continue = (ImageView)Pause_Menu.findViewById(R.id.Continue);
        ImageView Return_Main = (ImageView)Pause_Menu.findViewById(R.id.Return_Main);


        Continue.setOnClickListener(Continue_List);
        Return_Main.setOnClickListener(Main_Menu_List);
    }

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

以下是MainMenu.java的代码：

package com.example.deepseadiver;

//Imports the Required Android libaries
import android.content.Intent;
import android.graphics.Typeface;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;

//Declaration of the Main Menu
public class MainMenu extends ActionBarActivity {

    //Creates the Code Views
    MediaPlayer MainMenuMusic;
    RelativeLayout Start;
    ImageView ImageButton;
    TextView txt;




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

        //Creates a code representation of a graphical object on activity_main_menu
        Start = (RelativeLayout) findViewById(R.id.Button_Start);
        ImageButton = (ImageView) findViewById(R.id.Image_Button);
        txt = (TextView) findViewById(R.id.Text_Start);

        //Imprts a Custom Font
        Typeface Adventure = Typeface.createFromAsset(getAssets(), "Adventure.ttf");
        txt.setTypeface(Adventure);

        //Detects the user touch on Main Menu and changes button appearance
        Start.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                // TODO Auto-generated method stub
                return false;
            }
        });

        //Detects a user Click on Main Menu and starts the next activity
        Start.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                Intent Start_Game = new Intent(MainMenu.this, Game.class);
                startActivity(Start_Game);
            }
        });

    }



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

以下是activity_game.xml的代码：

这是我的清单文件：

        >
        <activity
            android:name="MainMenu"
            android:label="@string/app_name">
            <intent-filter>

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity

            android:label="@string/title_activity_game">
        </activity>
    </application>

</manifest>

对不起，我知道这是很多代码，但我花了好几个小时看着它，无法找到问题，我们非常感谢任何帮助。

Answer 1

你从这一行得到例外 -

Typeface Adventure = Typeface.createFromAsset(getAssets(), "Adventure.ttf");

唯一可能的原因是您的字体路径参数"Adventure.ttf"不正确。确保已将ttf文件放在eclipse项目的assets/Adventure.ttf路径中。

Eclipse“抱歉应用程序意外停止”
