无法使用扩展 SeekBar 的自己的类运行 Android 应用程序

发布于 2024-10-29 06:19:36 字数 13052 浏览 2 评论 0原文

我正在尝试编写 SeekBar 的扩展来自定义它的行为。

我在让新类的最基本形式在模拟器中运行时遇到问题。

我什至无法获得一个不添加任何新功能来启动的类。

谁能告诉我我在这里错过了什么基本的东西？ 当我尝试使用 ExtendedSeekBar 时，为什么应用程序无法正确初始化？ 在哪里可以找到已发生的异常的详细信息？

我在 XP 上运行 Eclipse，使用 Android SDK 工具修订版 10。 我还应该提供哪些其他信息？

感谢您的任何帮助。

这是我正在尝试做的事情的细节。

从 Hello World 教程应用程序开始，我扩展 main.xml 以包含标准 SeekBar 并更新 HelloAndroid.java 以查找对象并将进度设置为 25。

这是 main.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<SeekBar
    android:id="@+id/SeekBar01"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    />
</LinearLayout>

这是 HelloAndroid.java：

package com.example.helloandroid;

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

public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        SeekBar vSeekBar1 = (SeekBar)findViewById(R.id.SeekBar01);
        vSeekBar1.setProgress(25);
    }
}

我运行这个，没有问题，SeekBar 出现在模拟器上的应用程序中，并且进度设置正确，

到目前为止没有问题...

所以，现在我想开始扩展 SeekBar。

我更新 main.xml 以将 SeekBar 更改为 ExtendedSeekbar

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<ExtendedSeekBar
    android:id="@+id/SeekBar01"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    />
</LinearLayout>

和 HelloAndroid.java 以查找新对象

package com.example.helloandroid;

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

public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ExtendedSeekBar vSeekBar1 = (ExtendedSeekBar)findViewById(R.id.SeekBar01);
        vSeekBar1.setProgress(25);
    }
}

我创建一个新类，其中仅包含新的构造函数和每个构造函数调用的初始化函数（因此我可以设置单个断点

） .java

package com.example.helloandroid;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.SeekBar;

public class ExtendedSeekBar extends SeekBar {

    public ExtendedSeekBar(Context context) {
        super(context);
        Initialise();
    }

    public ExtendedSeekBar(Context context, AttributeSet attrs) {
        super(context, attrs);
        Initialise();
    }

    public ExtendedSeekBar(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        Initialise();
    }

    void Initialise(){
        Log.i("ESB","ExtendedSeekBar Initialise ");
    }
}

现在，当我运行它时，我会看到调试视图，并显示以下堆栈转储

，应用程序出现在模拟器中，没有 main.xml 指定的任何项目，只有标题栏。没有遇到我在 ExtendedSeekBar::initialise 中设置的断点。

原文

I'm trying to write an extension to SeekBar to customise it's behaviour.

I'm having problems getting the most basic form of the new class to run in the emulator.

I can't even get a class that doesn't add any new functionality to start up.

Can anybody tell me what basic thing I'm missing out here?
Why won't the app initialise correctly when I try to use an ExtendedSeekBar?
Where do I find details of the exception that has occurred?

I running Eclipse on XP, using Android SDK tools revision 10.
What other information should I provide?

Thanks for any help.

Here's the detail of what I'm trying to do.

Starting from the Hello World tutorial app I extend main.xml to include a standard SeekBar and update HelloAndroid.java to find the object and set the progress to 25.

Here's main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<SeekBar
    android:id="@+id/SeekBar01"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    />
</LinearLayout>

and here's HelloAndroid.java:

package com.example.helloandroid;

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

public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        SeekBar vSeekBar1 = (SeekBar)findViewById(R.id.SeekBar01);
        vSeekBar1.setProgress(25);
    }
}

I run this and, no problem, the SeekBar appears in the app on the emulator with tthe progress correctly set

No problems so far...

So, now I want to start to extend the SeekBar.

I update main.xml to change SeekBar to ExtendedSeekbar

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<ExtendedSeekBar
    android:id="@+id/SeekBar01"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    />
</LinearLayout>

and HelloAndroid.java to find the new object

package com.example.helloandroid;

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

public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ExtendedSeekBar vSeekBar1 = (ExtendedSeekBar)findViewById(R.id.SeekBar01);
        vSeekBar1.setProgress(25);
    }
}

I create a new class that just contains the new Constructors and an initialise function that is called by each constructor (so I can set a single breakpoint)

ExtendedSeekBar.java

package com.example.helloandroid;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.SeekBar;

public class ExtendedSeekBar extends SeekBar {

    public ExtendedSeekBar(Context context) {
        super(context);
        Initialise();
    }

    public ExtendedSeekBar(Context context, AttributeSet attrs) {
        super(context, attrs);
        Initialise();
    }

    public ExtendedSeekBar(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        Initialise();
    }

    void Initialise(){
        Log.i("ESB","ExtendedSeekBar Initialise ");
    }
}

Now, when I run it I get the Debug View appear with the following stack dump
