在我的代码中，除了完成之外，所有按键都能正常工作，因此请告诉我有关 DONE 键的建议。 我的代码如下：
我的mainActivity代码低于
package nl.fampennings.keyboard;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;
public class MainActivity extends Activity {
CustomKeyboard mCustomKeyboard;
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mCustomKeyboard= new CustomKeyboard(this, R.id.keyboardview, R.xml.hexkbd);
mCustomKeyboard.registerEditText(R.id.edittext0);
mCustomKeyboard.registerEditText(R.id.edittext1);
mCustomKeyboard.registerEditText(R.id.edittext2);
mCustomKeyboard.registerEditText(R.id.edittext3);
mCustomKeyboard.registerEditText(R.id.edittext4);
}
@Override public void onBackPressed() {
// NOTE Trap the back key: when the CustomKeyboard is still visible hide it, only when it is invisible, finish activity
if( mCustomKeyboard.isCustomKeyboardVisible() ) mCustomKeyboard.hideCustomKeyboard(); else this.finish();
}
boolean displayMsg(){
boolean flag=true;
if(flag)
{
Toast.makeText(this, "adfdf", 100).show();
}
return true;
}
}

NOTE When we add a horizontalGap in pixels, this interferes with keyWidth in percentages adding up to 100%
NOTE When we have a horizontalGap (on Keyboard level) of 0, this make the horizontalGap (on Key level) to move from after the key to before the key... (I consider this a bug)

答案 0 :(得分：1)
因为你做错了（int enter = 13）。不是这样，您可以尝试创建自己的代码，并在按下时执行任何操作。首先，在键盘xml处为“DONE”按钮创建自定义代码。我为此选择了数字-10：
<Key android:codes="-10" android:keyLabel="DONE" android:keyWidth="25%p" android:horizontalGap="6.25%p" android:keyEdgeFlags="left" />
在CustomerKeyboard类中为“enter”变量设置相同的代码：
public final static int enter = -10;
现在设置按下DONE时会发生什么：
else if(primaryCode==enter)
{
edittext.setText("");
main.displayMsg();
}
对不起我的英语，我希望你能理解。
答案 1 :(得分：0)
完成关键操作可能是
ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
如下所示： http://code.tutsplus.com/tutorials/create-a-custom-keyboard-on-android--cms-22615
答案 2 :(得分：0)
ACTION_UP对我来说还不够。您还需要ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_ENTER));
之后立即模仿实际按键：
Environment.CurrentDirectory
