我想通过在编辑文本中使用这些输入值的值，在单独的对话框中以详细方式提供用户在 EditText 中输入的输出。任何帮助将不胜感激。
代码如下:
EditText editText1,editText2,editText3;
Button btn,btn2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.btn);
btn2 = (Button) findViewById(R.id.btn2);
editText1 = (EditText) findViewById(R.id.editText2);
editText2 = (EditText) findViewById(R.id.editText3);
editText3 = (EditText) findViewById(R.id.editText4);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
calculate();
}
});
btn2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(MainActivity.this);
String s = " (Result) ";
alertDialogBuilder.setTitle("Detailed Output is");
alertDialogBuilder.setCancelable(false);
alertDialogBuilder.setMessage("(The code should be like as follows)\n\n"+"sum of entered number is:"+s+"\n"+"multiply of entered number is:"+s+"\n"+"subtraction of entered number is:"+s)
.setNeutralButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}
});
}
public void calculate() {
String a = editText1.getText().toString();
String b = editText2.getText().toString();
editText3.setText(String.valueOf(Integer.parseInt(a)+ Integer.parseInt(b))+"\n"+String.valueOf(Integer.parseInt(a)* Integer.parseInt(b))+"\n"+String.valueOf(Integer.parseInt(a)-Integer.parseInt(b)));
}
}
最佳答案
您可以使用 String.Format 使用输入参数来格式化您的字符串。
alertDialogBuilder.setMessage(String.format("(The code should be like as follows)\n\n"+"sum of entered number is:%s\n multiply of entered number is:%s \n subtraction of entered number is:%s"),editText1.getText().toString(), editText2.getText().toString(), editText3.getText().toString())
