推荐答案

添加您的EditText一个的LinearLayout内，设置页边距到布局。见下图：

add your edittext inside a linearlayout and set margins to that layout. see below:

    AlertDialog.Builder alert = new AlertDialog.Builder(this);

    alert.setTitle("Test");

    LinearLayout layout = new LinearLayout(this);
    layout.setOrientation(LinearLayout.VERTICAL);
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
         LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    params.setMargins(20, 0, 30, 0);

    EditText textBox = new EditText(myActivity.this);
    layout.addView(textBox, params);

    alert.setView(layout);

    alert.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
        // do nothing 
        }
    });

    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
    // do nothing
    }
    });

    alert.show();
