Question

我创建了一个自定义EditText。现在的问题是，当用户点击按钮时，我不知道如何从EditText获取数据。

这是Login.xml代码

<com.amar.MyCustomEditText
            android:id="@+id/etmob"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint="Enter your Mobile no"
            android:phoneNumber="true">
 </com.amar.MyCustomEditText>

        <Button
            android:id="@+id/loginbutton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="right"
            android:background="@drawable/submit" />.

这是我的java代码

@Override
protected void onCreate(Bundle savedInstanceState) {

    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.login);
    Button submit = (Button) findViewById(R.id.loginbutton);

    submit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // TODO Auto-generated method stub
            EditText et = (EditText) findViewById(R.id.etmob);
            String mobileno = et.getText().toString();
            if(mobileno == 1234567890)
           {
            Intent iv = new Intent(getApplicationContext(),Verify.class);
               startActivity(iv);
           }
             }
    });

这是MyCustomEditText.java

        public class MyCustomEditText extends EditText {
private Rect mRect;
private Paint mPaint;

public MyCustomEditText(Context context, AttributeSet attrs) {
    super(context, attrs);

    mRect = new Rect();
    mPaint = new Paint();
    // define the style of line
    mPaint.setStyle(Paint.Style.FILL_AND_STROKE);
    // define the color of line
    mPaint.setColor(Color.parseColor("#B1B0B0"));
}

@Override
protected void onDraw(Canvas canvas) {
    int height = getHeight();
    int lHeight = getLineHeight();
    // the number of line
    int count = height / lHeight;
    if (getLineCount() > count) {
        // for long text with scrolling
        count = getLineCount();
    }
    Rect r = mRect;
    Paint paint = mPaint;

    // first line
    int baseline = getLineBounds(0, r);

    // draw the remaining lines.
    for (int i = 0; i < count; i++) {
        canvas.drawLine(r.left, baseline + 10, r.right, baseline + 10,
                paint);
        // next line
        baseline += getLineHeight();
    }
    super.onDraw(canvas);
}
  }

Answer 1

MyCustomEditText _et = (MyCustomEditText)findviewbyid(R.id.etmob);
String _enteredvalue = _et.gettext.tostring();
sysyem.out.println(_enteredvalue);

请尝试

MyCustomEditText editText = (MyCustomEditText) findViewById(R.id.etmob);
String mobileno = editText.getText().toString();
if(mobileno.equalsIgnoreCase("1234567890"))

            String mobileno = et.getText().toString();
            if(mobileno.equalsIgnoreCase("1234567890"))
           {
            Intent iv = new Intent(getApplicationContext(),Verify.class);
               startActivity(iv);
           }
             }
    });

问题是，您没有初始化自己的自定义Edittext，而是使用Android默认Edittext。

submit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // TODO Auto-generated method stub
            com.amar.MyCustomEditText et = (com.amar.MyCustomEditText) findViewById(R.id.etmob);
            String mobileno = et.getText().toString();
            if(mobileno.equalsIgnoreCase("1234567890"))
           {
            Intent iv = new Intent(getApplicationContext(),Verify.class);
               startActivity(iv);
           }
             }
    });

Answer 4

试试此代码

MyCustomEditText editText = (MyCustomEditText)findViewById(id of the view);
String value = editText.getText().toString();
if(value=="1234567890"){
           //ToDo something
 }else{
           //ToDo something
 }
