我目前正在编写一个Android应用程序，但我对Java很新，所以我不太了解。我有一个活动（下面的那个）但是当我启动它时它强制关闭。 Eclipse没有检测到任何错误，我也没有检测到错误（但这只是正常的lol）。请你告诉我我错了什么以及如何解决它。谢谢 ：） PS：名为app_name的字符串很好。这不是错误。
package com.rezoluz.fsx_pocket;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;
public class Shortcuts extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.shortcuts);
Spinner selection = (Spinner) findViewById(R.id.shortcutsSpinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.shortcut_selection, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
selection.setAdapter(adapter);
selection.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
TextView Text = (TextView)findViewById(R.id.shortcutsText);
Text.setText(R.string.app_name);
}
});
}
}
编辑： Logcat得到了这个，我现在明白了这个错误，但是不知道怎么修复它......

更具体地说：
Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead
答案 0 :(得分：1)
selection.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
TextView Text = (TextView)findViewById(R.id.shortcutsText);
Text.setText(R.string.app_name);
}
});
将上面的OnClickListener代码替换为以下代码：
selection.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
TextView Text = (TextView)findViewById(R.id.shortcutsText);
Text.setText(R.string.app_name);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
答案 1 :(得分：0)
我同意，Log cat会让这更容易。蝙蝠，似乎你有两个不同的旋转器
simple_spinner_dropdown_item
和
simple_spinner_item
或错字;）
答案 2 :(得分：0)
您的错误很明确：
Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead
请改为尝试setOnItemClickListener。
I.E selection.setOnItemClickListener。
selection.setOnItemClickListener(new AdapterView.onItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
// Code
}
});
