public void openKeyboard(View view) {

    // 获取焦点

    editText2.setFocusable(true);

    editText2.requestFocus();

    // 弹出软键盘

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

    imm.showSoftInput(editText2, 0);

}

/**

 * Synonym for {@link #showSoftInput(View, int, ResultReceiver)} without a result receiver: explicitly request that the current input method's soft input area be shown to the user, if needed.

 *

 * @param view The currently focused view, which would like to receive soft keyboard input.

 * @param flags Provides additional operating flags.  Currently may be 0 or have the {@link #SHOW_IMPLICIT} bit set.

    return showSoftInput(view, flags, null);
