我'我试图创建一个应用程序,其中当按下按钮时,按钮是b1,调用toast从输入中获取数字并从textfield中提供字符串文本。我在logcat下面有一些错误。
MainActivity.java
package com.x.losey;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
import java.net.NetworkInterface;
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);
final Button b = (Button) (findViewById(R.id.Button2));
final Button b1 = (Button) (findViewById(R.id.button));
final EditText txt = (EditText) (findViewById(R.id.editText));
final EditText num = (EditText) (findViewById(R.id.editText2));
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
boolean a1 ;
Intent first = new Intent(MainActivity.this,second.class);
Toast.makeText(MainActivity.this, "OK" , Toast.LENGTH_SHORT).show();
startActivity(first);
}
});
b1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
int i;
int n;
n = Integer.parseInt(String.valueOf(num));
while(n!=0) {
String ab = txt.getText().toString();
Toast.makeText(MainActivity.this, ab, Toast.LENGTH_SHORT).show();
n--;
}
}
});
return true;
}
}
activity_main.xml中

当按钮= b1被点击时,我得到了吐司,但只有4或2次,当我删除n然后我添加一个值,然后我得到一个正确的输出。
这个Logcat错误是什么?

答案 0 :(得分:-1)
将MainActivity更改为:
private Button b;
private Button b1;
private EditText txt;
private EditText num;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b = (Button) findViewById(R.id.Button2);
b1 = (Button) findViewById(R.id.button);
txt = (EditText) findViewById(R.id.editText);
num = (EditText) findViewById(R.id.editText2);
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
boolean a1 ;
Intent first = new Intent(MainActivity.this,second.class);
Toast.makeText(MainActivity.this, "OK" , Toast.LENGTH_SHORT).show();
startActivity(first);
}
});
b1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
int i;
int n;
n = Integer.parseInt(String.valueOf(num));
while(n!=0)
{
String ab = txt.getText().toString();
Toast.makeText(MainActivity.this, ab, Toast.LENGTH_SHORT).show();
n--;
}
}
});
}
@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;
}
}
