我创建了类ComplexEditText，该类是从AppCompatEditText扩展的。我确定了背景变体：
setBackground(getResources().getDrawable(R.drawable.backgroundedittext));
我选择了填充：
setPadding((int) (16 * scale), (int) (10 * scale), (int) (17 * scale), (int) (13 * scale));
我创建了清除输入文字的按钮
mClearButtonImage = ResourcesCompat.getDrawable(getResources(), R.mipmap.delete_button, null);
但是问题是，当我触摸自定义视图（从AppCompatEditText扩展）时，键盘无法打开。我尝试过：
setClickable(true)
setFocusable(true)
setShowSoftInputOnFocus(true);
nputMethodManager imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT);
我住进AndroidManifes.xml：
android:windowSoftInputMode="adjustResize"
它也不起作用。键盘没有出现。

答案 0 :(得分：0)
我在构造函数中添加以下行：
clearFocus();
，然后在onTouch方法中添加以下代码：
requestFocus();
InputMethodManager imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
