前言：最初实现评论的时候，我是在利用setVisibility来控制输入框的隐藏与显示来实现评论。但是发现这样做，弹出键盘的时候会把整个界面推上去，不大符合人们的使用习惯。因此，我决定采用弹窗的形式来实现评论与回复。
记录下用到的场景：1、点击评论ICON，2、点击评论列表进行回复
public class PlDialog extends DialogFragment {
//点击发表，内容不为空时的回调
public SendBackListener sendBackListener;
public interface SendBackListener{
void sendBack(String inputText);
}
private String texthint;
private Dialog dialog;
private EditText inputDlg;
private int numconut=300;
private String tag=null;
public PlDialog() {
}
@SuppressLint("ValidFragment")
public PlDialog(String texthint, SendBackListener sendBackListener){//提示文字
this.texthint=texthint;
this.sendBackListener=sendBackListener;
}
public Dialog onCreateDialog(Bundle savedInstanceState) {
// 使用不带Theme的构造器, 获得的dialog边框距离屏幕仍有几毫米的缝隙。
dialog = new Dialog(getActivity(), R.style.PlDialog);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); // 设置Content前设定
// getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
View contentview = View.inflate(getActivity(), R.layout.comment_dialog_layout, null);
dialog.setContentView(contentview);
dialog.setCanceledOnTouchOutside(true); // 外部点击取消
// 设置宽度为屏宽, 靠近屏幕底部。
Window window = dialog.getWindow();
WindowManager.LayoutParams lp = window.getAttributes();
lp.gravity = Gravity.BOTTOM; // 紧贴底部
lp.alpha = 1;
lp.dimAmount = 0.5f;
lp.width = WindowManager.LayoutParams.MATCH_PARENT; // 宽度持平
window.setAttributes(lp);
window.addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
inputDlg = (EditText) contentview.findViewById(R.id.dialog_comment_content);
inputDlg.setHint(texthint);
final TextView tv_send = (TextView) contentview.findViewById(R.id.dialog_comment_send);
inputDlg.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
if (s.length() > 0) {
tv_send.setBackgroundResource(R.drawable.corners_review_cansend);
} else {
tv_send.setBackgroundResource(R.drawable.corners_review_send);
}
}
});
tv_send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (TextUtils.isEmpty(inputDlg.getText().toString())) {
Toast.makeText(getActivity(),"输入内容为空",Toast.LENGTH_LONG).show();
return;
} else {
sendBackListener.sendBack(inputDlg.getText().toString());
}
}
});
inputDlg.setFocusable(true);
inputDlg.setFocusableInTouchMode(true);
inputDlg.requestFocus();
final Handler hanler = new Handler();
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
public InputMethodManager mInputMethodManager;
@Override
public void onDismiss(DialogInterface dialog) {
hanler.postDelayed(new Runnable() {
@Override
public void run() {
hideSoftkeyboard();
}
}, 200);
}
});
return dialog;
}
public void hideSoftkeyboard() {
try {
((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE))
.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(),
InputMethodManager.HIDE_NOT_ALWAYS);
} catch (NullPointerException e) {
}
}
}
上面的代码是弹出框的代码，如何使用呢？
dialog = new PlDialog("评论：", new PlDialog.SendBackListener() {
@Override
public void sendBack(final String inputText) {
//Toast.makeText(MyApplication.getContextObject(),inputText,Toast.LENGTH_SHORT).show();
final String[] s = pinStr.split("#");
//Toast.makeText(MyApplication.getContextObject(),pinStr,Toast.LENGTH_SHORT).show();
pinglun("pl",s,mData.get(position1).getDy_id()+"",inputText);
dialog.dismiss();
}
});
dialog.show(getFragmentManager(), "dialog");
如果是回复的话，就修改上段代码中的“评论：”即可。
