Question

首先抱歉我的英语不好，希望你能理解我。我在Android Studio上制作Android应用程序。我在这里是因为我开始第三次活动时我的应用程序崩溃了。

好吧，我有三个活动。从第一个开始到第二个从第二个到第一个效果很好，但是当我尝试从第二个进入第三个时，我按下按钮进入第三个活动，我的应用程序崩溃，它说“不幸的是，Project Saya已经停止。“

这是我的activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.missmagius.projectsaya.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Merhaba, Project Saya'ya hoşgeldiniz! Başlamadan önce sorun yaşamamak için lütfen talimatları gözden geçirin. İyi eğlenceler!"
        android:id="@+id/textView"
        android:enabled="false"
        android:textColor="@color/abc_input_method_navigation_guard" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Talimatlar"
        android:id="@+id/buttonActOne"
        android:layout_marginTop="29dp"
        android:layout_below="@+id/textView"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />
</RelativeLayout>

这是MainActivity.java

    package com.missmagius.projectsaya;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

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

        Button btnOne =(Button)findViewById(R.id.buttonActOne);
        btnOne.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent=new Intent(getApplicationContext(),ActivityTwo.class);
                startActivity(intent);
            }
        });


    }
}

这是activity_two.xml

package com.missmagius.projectsaya;

                startActivity(intent);
            }
        });


    }
}

这是ActivityTwo.java

package com.missmagius.projectsaya;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

    Button btnTwo;
    Button getBtnTwo;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_two);

        Button btnTwo =(Button)findViewById(R.id.buttonActTwo);
        Button btnThree=(Button)findViewById(R.id.buttonActThree);

        btnTwo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent2 = new Intent(ActivityTwo.this,MainActivity.class);
                startActivity(intent2);
            }
        });

        btnThree.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent4 = new Intent(ActivityTwo.this,SpeechActivity.class);
                startActivity(intent4);
            }
        });
    }

}

就是这样。我不知道我哪弄错了。我需要你的帮助。感谢。

Answer 1

将android:src="@+id/micc"更改为android:src="@drawable/micc" />中的ImageButton。它导致了这个问题。

Answer 2

更改以下代码

**

Intent intent=new Intent(getApplicationContext(),ActivityTwo.class);
startActivity(intent);

**

致：

**

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

**

Answer 3

除非Intent包含FLAG_ACTIVITY_NEW_TASK标志，否则不允许应用程序上下文启动活动。

只需改变（至少）

Intent intent=new Intent(getApplicationContext(),ActivityTwo.class);
startActivity(intent);

致：

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

在MainActivity

中的clickListener内

Answer 4

您错过了完成旧活动，只需在finish()

之后添加startActivity()即可

所以这是代码：

startActivity(i);
finish();

当我点击按钮时，我的应用程序崩溃，这将带我另一个Java，Android Studio上的活动
