我已经宣布了一个EditText数组＆＃34; ed [] []＆＃34;在onBoxListener中的alertBox中。我在同一个活动中的另一个onClickListener方法中使用了这个ed [] []引用，但它总是给出以下错误
ed无法解析为变量
这是我的代码：
private EditText nR,nC,nR1,nC1;
EditText[][] arr;
private Button submit,b2,bmul;
private LinearLayout matrix,matrix2;
int rows,cols,a1=1,b1=1,a3,b3;
private LinearLayout layout,layout2;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.dimensions);
matrix = (LinearLayout) findViewById(R.id.matrix);
matrix2 = (LinearLayout) findViewById(R.id.matrix2);
matrix.setOrientation(LinearLayout.VERTICAL);
matrix2.setOrientation(LinearLayout.VERTICAL);
submit = (Button) findViewById(R.id.button1);
b2 = (Button) findViewById(R.id.button2);
bmul=(Button)findViewById(R.id.mul);
submit.setOnClickListener(this);
b2.setOnClickListener(this);
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch(arg0.getId()){
case R.id.button1:
//creatDialog(matrix,submit);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
alert.setTitle("Define Dimensions");
alert.setMessage("Assign Numbers of Rows and Columns to Matrix");
//Set an EditText view to get user input
final View tex =inflater.inflate(R.layout.dialog_dimension,null);
alert.setView(tex);
nR=(EditText)tex.findViewById(R.id.R2);
nC=(EditText)tex.findViewById(R.id.C2);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
a1 = Integer.parseInt(nR.getText().toString());
b1 = Integer.parseInt(nC.getText().toString());
submit.setText(""+a1+"x"+b1);
//multipleDimension(a1,b1,mat);
**final EditText ed[][] = new EditText[a1][b1];**
matrix.removeAllViews();
for (int i = 0; i < a1; i++) {
layout = new LinearLayout(
Dimensions.this);
layout.setOrientation(LinearLayout.HORIZONTAL);
for (int j = 0; j < b1; j++) {
ed[i][j] = new EditText(Dimensions.this);
//ed[i][j].setId(+(i)+(j));
ed[i][j].setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
ed[i][j].setHint("a"+(i+1)+(j+1));
ed[i][j].setTextColor(Color.RED);
layout.addView(ed[i][j]);
}
matrix.addView(layout);
}
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
}).show();
break;
case R.id.button2:
//creatDialog(matrix2,b2);
//creatDialog(matrix,submit);
AlertDialog.Builder alert1 = new AlertDialog.Builder(this);
LayoutInflater inflater1 = this.getLayoutInflater();
alert1.setTitle("Define Dimensions");
alert1.setMessage("Assign Numbers of Rows and Columns to Matrix");
//Set an EditText view to get user input
final View tex1 =inflater1.inflate(R.layout.dialog_dimension,null);
alert1.setView(tex1);
nR1=(EditText)tex1.findViewById(R.id.R2);
nC1=(EditText)tex1.findViewById(R.id.C2);
alert1.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
a3 = Integer.parseInt(nR1.getText().toString());
b3 = Integer.parseInt(nC1.getText().toString());
b2.setText(""+a3+"x"+b3);
//multipleDimension(a1,b1,mat);
final EditText ed1[][] = new EditText[a3][b3];
matrix2.removeAllViews();
for (int i = 0; i < a3; i++) {
layout2 = new LinearLayout(
Dimensions.this);
layout2.setOrientation(LinearLayout.HORIZONTAL);
for (int j = 0; j < b3; j++) {
ed1[i][j] = new EditText(Dimensions.this);
//ed[i][j].setId(+(i)+(j));
ed1[i][j].setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
ed1[i][j].setHint("a"+(i+1)+(j+1));
ed1[i][j].setTextColor(Color.RED);
layout2.addView(ed1[i][j]);
}
matrix2.addView(layout2);
}
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
}).show();
break;
}
bmul.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent=new Intent(Dimensions.this,ArithmaticOperation.class);
String s[][]= new String[a1][b1];
intent.putExtra("m", a1);
intent.putExtra("n", b1);
for (int i=0;i<a1; i++){
for (int j=0;j<a1; j++){
s[i][j]=**ed[i][j]**.getText().toString();
intent.putExtra("key["+i+"]["+j+"]", s[i][j]);
}
}
}
});
}
}
这里我实例化EditText数组
case R.id.button1:
//creatDialog(matrix,submit);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
alert.setTitle("Define Dimensions");
alert.setMessage("Assign Numbers of Rows and Columns to Matrix");
//Set an EditText view to get user input
final View tex =inflater.inflate(R.layout.dialog_dimension,null);
alert.setView(tex);
nR=(EditText)tex.findViewById(R.id.R2);
nC=(EditText)tex.findViewById(R.id.C2);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
a1 = Integer.parseInt(nR.getText().toString());
b1 = Integer.parseInt(nC.getText().toString());
submit.setText(""+a1+"x"+b1);
//multipleDimension(a1,b1,mat);
**final EditText ed[][] = new EditText[a1][b1];**
matrix.removeAllViews();
for (int i = 0; i < a1; i++) {
layout = new LinearLayout(
Dimensions.this);
layout.setOrientation(LinearLayout.HORIZONTAL);
for (int j = 0; j < b1; j++) {
ed[i][j] = new EditText(Dimensions.this);
//ed[i][j].setId(+(i)+(j));
ed[i][j].setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
ed[i][j].setHint("a"+(i+1)+(j+1));
ed[i][j].setTextColor(Color.RED);
layout.addView(ed[i][j]);
}
matrix.addView(layout);
}
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
}).show();
break;
在这里我得到了错误
bmul.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent=new Intent(Dimensions.this,ArithmaticOperation.class);
String s[][]= new String[a1][b1];
intent.putExtra("m", a1);
intent.putExtra("n", b1);
for (int i=0;i<a1; i++){
for (int j=0;j<a1; j++){
s[i][j]=**ed[i][j]**.getText().toString();
intent.putExtra("key["+i+"]["+j+"]", s[i][j]);
}
}
}
});
答案 0 :(得分：0)
private EditText nR, nC, nR1, nC1;
EditText[][] arr;
private Button submit, b2, bmul;
private LinearLayout matrix, matrix2;
int rows, cols, a1 = 1, b1 = 1, a3, b3;
private LinearLayout layout, layout2;
final EditText ed[][] = new EditText[a1][b1];
final EditText ed1[][] = new EditText[a3][b3];
将ed和ed1的声明移到班级的顶部。
