我一直在使用 android 应用程序时遇到困难。我正在使用 Eclipse，V 4.2.0，并运行 API 版本 7。下面是我遇到困难的一个程序的 LogCat 输出。这是我的代码：

显现

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.deadEddie.counter"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="7"
    android:targetSdkVersion="15" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
</application>

</manifest>

布局（activity_main.xml）

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

    android:text="@string/text"

    android:gravity="center"
    android:id="@+id/tvDisplay"

    />

 <Button
    android:id="@+id/btnAdd"
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    android:text="@string/btn1Title"
    android:layout_gravity="center"

  <Button
    android:id="@+id/btnSubtract"
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    android:text="@string/btn2Title"
    android:layout_gravity="center"
    />


</LinearLayout>

MainActivity.java

package com.deadEddie.counter;

import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends Activity 
{
int counter;
Button add;
Button subtract;
TextView display;

@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    counter = 0;
    add = (Button) findViewById(R.id.btnAdd);
    subtract = (Button) findViewById(R.id.btnSubtract);
    display = (TextView) findViewById(R.id.tvDisplay);

    add.setOnClickListener(new View.OnClickListener() 
    {

        @Override
        public void onClick(View v) 
        {
            // TODO Auto-generated method stub
            counter ++;
            display.setText("Counter = " + counter);

        }
    });
    subtract.setOnClickListener(new View.OnClickListener() 
    {

        @Override
        public void onClick(View v) 
        {
            // TODO Auto-generated method stub
            counter --;
            display.setText("Counter = "+ counter);
        }
    });

}
}

LogCat 输出：

我认为您需要将颜色声明移出 strings.xml 并将其放入 colors.xml

颜色.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="myColor">#ccff00</color>
</resources>

然后在您的布局中像这样引用它：

<TextView

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textColor="@color/myColor"
android:textSize="30dp"
android:text="@string/text"
android:textStyle="bold"
android:gravity="center"
android:id="@+id/tvDisplay"

/>

在您的 xml 中，这一行是错误的：

android:textColor="@string/color

您应该检查您是否有一个名为“/res/color/color.xml”的文件，其中包含一些对颜色的引用。

或者只是改变：

android:textColor="@string/color

到 android:textColor="#ff000000"
