我是Android的新手制造的转换器应用程序在Xperia z2和三星j2上工作正常，但是当我尝试在Xperia z1上测试它时崩溃。该应用程序根本没有启动。 我经历了很多帖子，但无法解决问题 它给了我这个错误：

java.lang.RuntimeException: Unable to start activity 
ComponentInfo{com.example.sreyash.uconverter/com.example.sreyash.uconverter

这是指向以下内容的代码错误：

 <android.support.constraint.ConstraintLayout 
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="@drawable/converter_background"
  tools:context=".MainActivity">

    <ImageButton
    android:id="@+id/length"
    android:layout_width="45dp"
    android:layout_height="45dp"
    android:layout_marginBottom="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    android:onClick="onClick"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.549"
    android:background="@drawable/lengths_symbol" />

    <Spinner
    android:id="@+id/spinner"
    android:layout_width="150dp"
    android:layout_height="30dp"
    android:layout_marginBottom="8dp"
    android:layout_marginTop="8dp"
    android:entries="@android:color/background_light"

    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.110000014" />

这是主要的活动; 

public class MainActivity extends Activity implements 
AdapterView.OnItemSelectedListener{



int mode_flag;
ArrayAdapter<CharSequence> adapter1;
ArrayAdapter<CharSequence> adapter2;
Spinner spinner1;
Spinner spinner2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     spinner1=findViewById(R.id.spinner);
     spinner2=findViewById(R.id.spinner2);

    mode_flag=1;
    set_adapter(R.array.Length);
    Lenght.setBackgroundResource(R.drawable.lengths_symbol_clicked);
    Title.setText(R.string.Lenght_title);
    conversion_mode="Length";

    Clear.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(!input.isEmpty()) {
                input = input.substring(0, input.length() - 1);
                Log.d("back", ""+input);
                inputview.setText(input);
            }

            Conversion();
        }
    });
    Clear.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            return false;
        }
    });


}

   public void set_adapter(int source){
    adapter1=ArrayAdapter.createFromResource(this, 
   source,android.R.layout.simple_spinner_item);
    adapter2=ArrayAdapter.createFromResource(this, 
source,android.R.layout.simple_spinner_item);
adapter1.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);

adapter2.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);

    spinner1.setAdapter(adapter1);
    spinner1.setOnItemSelectedListener(this);

    spinner2.setAdapter(adapter2);
    spinner2.setOnItemSelectedListener(this);

}

任何帮助将不胜感激

First Thing android：entries属性用于将数据绑定到微调器，而不是用于设置颜色。

  

XML方法

首先在String.xml文件中创建国家/地区数组

<div class="chat chat-right ">
   <div class="chat-avatar">
  <a class="avatar" data-toggle="tooltip" href="" data-placement="right" title="Backend">

你应该将android：entries =“@ android：color / background_light”更改为 机器人：项= “@阵列/ country_names”

  

JAVA代码方法

您可以将其创建为Java Code Like

使用带有Spinner的Contry和Bind Array使用ArrayAdapter创建ArrayList。

 <string-array name="country_names">
        <item>India</item>
        <item>United States</item>
        <item>Indonesia</item>
        <item>France</item>
        <item>Italy</item>
        <item>Singapore</item>
        <item>New Zealand</item>
    </string-array>

答案 1 :(得分：0)

从XML中删除android:entries="@android:color/background_light"并从代码中设置ArrayAdapter或在Spinner中使用ArrayList条目。

示例：在strings.xml中创建一个数组：

<string-array name="country_arrays">
    <item>Malaysia</item>
    <item>United States</item>
    <item>Indonesia</item>
    <item>France</item>
    <item>Italy</item>
    <item>Singapore</item>
    <item>New Zealand</item>
    <item>India</item>
</string-array>

并在XML中将android:entries="@android:color/background_light"更改为android:entries="@array/country_arrays"。
