Question

这是我向EditText添加边框的方法。如何才能在EditText的一侧添加边框，并定义边框的颜色和宽度？

EditText editText = new EditText(this);
editText.setText("Find");
editText.setWidth(555);

GradientDrawable border = new GradientDrawable();
border.setColor(0xFFFFFFFF);  // white background
border.setStroke(1, 0xFF000000);  // black border with full
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
    editText.setBackgroundDrawable(border);
} else {
    editText.setBackground(border);
}

Vielen dank im voraus。

To get border on one side, you can create your own drawable like this:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item>
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" />
    </shape>
  </item>
  <item android:right="5dp">
    <shape android:shape="rectangle">
      <solid android:color="#FFFF" />
    </shape>
  </item>
</layer-list>

And set this drawable as background to your EditText.

If you want to add border only one side of EditText then you should use View tag in your layout file to draw a simple line and place it near your EditText and use background property to set color of line. To draw horizontal line use this:

 <View
    android:layout_width="match_parent"
    android:background="@color/colorPrimary"
    android:layout_height="2dp" />
