推荐答案

import android.widget.Button;
import android.widget.EditText;    
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;

LinearLayout mLinearLayout = new LinearLayout(this);
mLinearLayout = (LinearLayout)findViewById(R.id.mylinearlayout);

Button lButton = (Button)findViewById(R.id.mybtnid);
lButton.setOnClickListener(new View.OnClickListener() {
    public void onClick(View arg0) {
        EditText lEditText = new EditText(this);
        lEditText .setLayoutParams(
            new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, 
                                          LayoutParams.WRAP_CONTENT));
        lEditText.SetText("Text Here");
        mLinearLayout.addView(lEditText);
        lEditText.setWidth(width);     // change width
        lEditText.setHeight(height);   // change height
        lEditText.setX(<x value>);     // set absolute position of x
        lEditText.setY(<y value>);     // set absolute position of y
    }
}

您也可以使用

int X = 50; // Arbitrary values - use whatever you want
int Y = 100;

lEditText.setPadding(X, Y, 0, 0);  // set x and y using padding
