我尝试使用 clickHandler 制作微调器和按钮
这是我的 nyoba.java
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.Spinner;
import android.widget.TextView;
public class nyoba extends Activity {
String[] nama_hari = {"Senin", "Selasa", "Rabu","Kamis","Jum'at","Sabtu","Minggu"};
/** Called when the activity is first created. */
Spinner spinner1;
Button btnSubmit;
TextView textView1;
String tes;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnSubmit = (Button)findViewById(R.id.btnSubmit);
textView1 = (TextView)findViewById(R.id.textView1);
spinner1 = (Spinner)findViewById(R.id.spinner1);
ArrayAdapter<String> aa = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, nama_hari);
aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(aa);
}
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
tes = nama_hari[arg2];
}
public void clickHandler(View view){
switch (view.getId()){
case R.id.btnSubmit:
textView1.setText(tes);
break;
}
}
}
这是我的 main.xml 文件
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#ffffff">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dip"
>
<Spinner
android:id="@+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="@+id/btnSubmit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="clickHandler"
android:text="Submit" />
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
</RelativeLayout>
</ScrollView>
但是当我将它运行到模拟器时,我在微调器中选择 1 个选项并单击按钮,TextView 不会显示我选择的微调器中的单词
(例如,我在微调器处选择“senin”,然后单击按钮,但文本“senin”没有出现在 TextView 中)
我检查了DDMS,没有错误.....
代码错了吗?你能帮我看看哪一个是错的吗?
还是谢谢....
