Android应用程序无法启动

标签： android eclipse launch

我已经制作了这个应用程序但是当我尝试启动它时会弹出一条消息说应用程序已停止。我真的找不到代码中的任何错误。   这是代码，只有很多ImageButtons：

package com.fanis.math;

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

public class MyResistance extends Activity implements OnClickListener {
View b1, b2, b3, b4, b5, b6, b7, b8, b9, b10, b11, b12;
Button bok, bclear;
TextView t;
int k = -1;
int[] ar = new int[4];
double n = 0;
double multi=0;
String nString;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.resistance);

    b1 = (ImageButton) findViewById(R.id.im1);
    b2 = (ImageButton) findViewById(R.id.im2);
    b3 = (ImageButton) findViewById(R.id.im3);
    b4 = (ImageButton) findViewById(R.id.im4);
    b5 = (ImageButton) findViewById(R.id.im5);
    b6 = (ImageButton) findViewById(R.id.im6);
    b7 = (ImageButton) findViewById(R.id.im7);
    b8 = (ImageButton) findViewById(R.id.im8);
    b9 = (ImageButton) findViewById(R.id.im9);
    b10 = (ImageButton) findViewById(R.id.im10);
    b11 = (ImageButton) findViewById(R.id.im11);
    b12 = (ImageButton) findViewById(R.id.im12);
    bok = (Button) findViewById(R.id.ok);
    bclear = (Button) findViewById(R.id.clear);
    t = (TextView) findViewById(R.id.tv1);
    b1.setOnClickListener(this);
    b2.setOnClickListener(this);
    b3.setOnClickListener(this);
    b4.setOnClickListener(this);
    b5.setOnClickListener(this);
    b6.setOnClickListener(this);
    b7.setOnClickListener(this);
    b8.setOnClickListener(this);
    b9.setOnClickListener(this);
    b10.setOnClickListener(this);
    b11.setOnClickListener(this);
    b12.setOnClickListener(this);
    bok.setOnClickListener(this);
    bclear.setOnClickListener(this);

}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.im1:
        k += 1;
        ar[k] = 0; // dianisma pou krataei kathe psifio
        break;
    case R.id.im2:
        k += 1;
        ar[k] = 1;
        break;
    case R.id.im3:
        k += 1;
        ar[k] = 2;
        break;
    case R.id.im4:
        k += 1;
        ar[k] = 3;
        break;
    case R.id.im5:
        k += 1;
        ar[k] = 4;
        break;
    case R.id.im6:
        k += 1;
        ar[k] = 5;
        break;
    case R.id.im7:
        k += 1;
        ar[k] = 6;
        break;
    case R.id.im8:
        k += 1;
        ar[k] = 7;
        break;
    case R.id.im9:
        k += 1;
        ar[k] = 8;
        break;
    case R.id.im10:
        k += 1;
        ar[k] = 9;
        break;
    case R.id.im11:
        k += 1;
        multi = 0.01;
        break;
    case R.id.im12:
        k += 1;
        multi = 0.1;
        break;
    case R.id.ok:
        for (int i = 1; i <= k; i++) {
            n = n + ar[i - 1] * Math.pow(10, k - i);
        }
        if (multi == 0) {
            multi = Math.pow(10, ar[k]);
        }
        n = n * multi;
        nString = String.valueOf(n) + "" + "Ω";
        t.setText(nString);
        break;
    case R.id.clear:
        t.setText("");
        n = 0;
        k = -1;
        multi=0;
    }

}

}   这就是明显的

这是布局虽然我不认为这是我无法启动应用程序的原因..

更改此行：

View b1, b2, b3, b4, b5, b6, b7, b8, b9, b10, b11, b12;

为：

ImageButton b1, b2, b3, b4, b5, b6, b7, b8, b9, b10, b11, b12;
