标签： android button start-activity

嗨，我是Android中的编码业余爱好者但我已经设法到目前为止但是已经提出了一个相对简单的问题， 第一个屏幕我插入一些文本然后打印到下一个屏幕，其中还有几个按钮，我还没有定义其中一个的意图， 它用于显示第二个活动，然后在第二个活动上单击按钮时强制关闭，但现在它甚至无法进入第二个活动。我想要的是第一个显示下一个活动的活动，按钮然后打开单独的活动可以有人告诉我哪里出错了吗？

bathactviity.java 

package com.example.myapplication;


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

public class bathactivity extends Activity {
Button button;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_bath);
    button = (Button)findViewById(R.id.nextbutton);




     }



}

activity_bath.xml 

<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">

<TextView
    android:layout_width="match_parent"
    android:layout_height="55dp"
    android:text="@string/bath"
    android:id="@+id/bath_text_View"
    android:textSize="20sp"
    android:gravity="center"
    android:textStyle="italic" />

<ImageView
    android:contentDescription="@string/bath"
    android:layout_width="match_parent"
    android:layout_height="404dp"
    android:id="@+id/imageView"
    android:layout_gravity="center"
    android:src="@drawable/getdressedimg" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/next"
    android:id="@+id/nextbutton"
    android:textSize="20sp"
    android:textStyle="bold|italic"
    android:layout_gravity="center" />
</LinearLayout>



secondactivity.java

package com.example.myapplication;

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

public class secondactivity extends Activity {
TextView t;
Button button;
Button button2;
Button button3;
Button button4;






 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);
    t = (TextView)findViewById(R.id.textView3);
    String n = this.getIntent().getStringExtra("NAMEDATA");
    t.setText(n);
    button = (Button)findViewById(R.id.button);
    button2 = (Button)findViewById(R.id.button2);
    button3 = (Button)findViewById(R.id.button3);
    button4 = (Button)findViewById(R.id.button4);

    setButtonOnClickListener();

  }


   private void setButtonOnClickListener(){
    Intent intent = new Intent(getApplicationContext(), bathactivity.class);
    startActivity(intent);
}






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

}

不要认为这是一个明显的问题，但以防万一

android manifest

<?xml version="1.0" encoding="utf-8"?>

    <activity
        android:name="com.example.myapplication.bathactivity"
        android:label="@string/title_activity_bath" >
    </activity>

  </application>

  </manifest>

这不能成为你要求的logcat吗？

答案 0 :(得分：4)

Out of memory on a 42701840-byte allocation. 当您尝试为imageview加载android:src="@drawable/getdressedimg"时，这看起来像内存不足问题。图像有多大？如果它太大，则需要缩小以匹配ImageView的高度和宽度。检查this page如何执行此操作。

答案 1 :(得分：0)

你没有提到默认的诅咒。像这样：

<activity
        android:name=".Bathactivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="com.example.myapplication.BATHACTIVITY" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

只需将上述代码复制并粘贴到manifest .xml中，而不是

<activity
    android:name="com.example.myapplication.secondactivity"
    android:label="@string/title_activity_second" >
</activity>
<activity
    android:name="com.example.myapplication.bathactivity"
    android:label="@string/title_activity_bath" >
</activity>
