我正在尝试为学校作业构建一个简单的应用程序。当用户点击图像按钮时,会打开一个新视图,其中包含图像的图片。但是,只要用户点击我的应用程序中的图像,它就会停止。 logcat错误说在android view.view.onclick上说,但我看不出错误在哪里。提前谢谢。
main_activity.java
package com.example.kids;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.widget.ImageButton;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void apple(ImageButton buttona){
Intent intent = new Intent(this, Apple.class);
startActivity(intent);
}
public void banana(ImageButton buttonb){
Intent intent = new Intent(this, Banana.class);
startActivity(intent);}
public void strawberry(ImageButton buttons){
Intent intent = new Intent(this, Strawberry.class);
startActivity(intent);
}}
Apple.java
package com.example.kids;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class Apple extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_apple);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.apple, menu);
return true;
}
}
activity_main.xml中
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="100"
android:orientation="vertical" >
<TextView
android:id="@+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="9.93"
android:text="Pick a fruit"
android:textAppearance="?android:attr/textAppearanceLarge" />
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="30"
android:src="@drawable/applebudget"
android:onClick="apple"
/>
<ImageView
android:id="@+id/imageView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="30"
android:src="@drawable/bananabudget"
android:onClick="banana"
/>
<ImageView
android:id="@+id/imageView3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="30"
android:src="@drawable/strawberrybudget"
android:onClick="strawberry"
/>
</LinearLayout>
答案 0 :(得分:2)
更改onClick()方法的方法签名:
public void apple(View buttona){}
public void banana(View buttonb){}
public void strawberry(View buttons){}
你完成了。
