1) 这是我的 xml list

package com.thenewboston.travis;


import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class Splash extends Activity{

@Override
protected void onCreate(Bundle InstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(InstanceState);
    setContentView(R.layout.splash);
    Thread timer = new Thread(){
        public void run(){
            try{
                sleep(5000);
            } catch (InterruptedException e){
                e.printStackTrace();
            }finally{
                Intent openStartingPoint = new       Intent("com.thenewboston.travis.STARTINGPOINT");
                startActivity(openStartingPoint);
            }
        }
    };
    timer.start();

}


}

2) 这是我的 splash java Activity

package com.thenewboston.travis;


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

public class startingPoint extends Activity {

int counter;
Button add, sub;
TextView display;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    counter = 0;
    add = (Button) findViewById(R.id.bAdd);
    sub = (Button) findViewById(R.id.bSub);
    display = (TextView) findViewById(R.id.tvDisplay);
    add.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            counter += 1;
            display.setText("Your total is" + counter);
        }
    });
    sub.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            counter -= 1;
            display.setText("Your total is" + counter);
        }
    });
}

}

3)那是我的起点 java Activity

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
tools:context=".MainActivity" >

<TextView
    android:id="@+id/tvDisplay"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:gravity="center"
    android:text= "@string/text"
    android:textSize="@string/text_size" />

<Button
    android:id="@+id/bAdd"
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="@string/atext"
    android:textSize="@string/btext_size" />

<Button
    android:id="@+id/bSub"
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="@string/stext"
    android:textSize="@string/btext_size" />

</LinearLayout>

4) 这是我的主要 xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" 
android:background="@drawable/splash">


</LinearLayout>

5)这是我的splash xml

6) 这是我的日志猫

7) 此代码运行初始屏幕，但当 5000 毫秒完成时它崩溃了？？？？

Answer 1

来自 LogCat:

Caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x3
    at android.content.res.TypedArray.getDimensionPixelSize(TypedArray.java:463)
    at android.widget.TextView.<init> (TextView.java:898)
    at android.widget.TextView.<init>   (TextView.java:556)

我不认为文本大小可以用字符串表示。

<TextView
    ...
    android:textSize="@string/text_size" />

尝试为所有 View 硬编码此值:

<TextView
    ...
    android:textSize="16sp" />

如果有效，请查看 Styles and Themes了解为每个 View 设置一种文本大小的适当方法。
