android评论区,Android类似朋友圈评论视图Dialog实现

很常见的一种成果，点击评论弹出输入框，点空白区域或点“发送”后输入框隐没并收起键盘，通常会遇到键盘遮挡输入框问题，应用Dialog的形式解决这个问题绝对简略点，更重要是能代码模块化减少复用性。

dialog_family_dynamic_comment.xml 评论布局文件

android:layout_height="match_parent"

android:background="@android:color/transparent">

public class FamilyDynamicCommentDialog extends Dialog {

private FamilyDynamicView familyDynamicView;

public FamilyDynamicCommentDialog(@NonNull Context context, FamilyDynamicView familyDynamicView) {

super(context, R.style.DialogFullScreen);

this.familyDynamicView = familyDynamicView;

Objects.requireNonNull(getWindow()).setBackgroundDrawable(new ColorDrawable());

View view = LayoutInflater.from(context).inflate(R.layout.dialog_family_dynamic_comment, null, false);

etContent = (EditText) view.findViewById(R.id.et_content);

Button btnSend = (Button) view.findViewById(R.id.btn_send);

setContentView(view);

view.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

dismiss();

}

});

btnSend.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

String content = etContent.getText().toString().trim();

if (content.length() == 0) {

Toast.makeText(getContext(), getContext().getString(R.string.toast_please_input_comment_content), Toast.LENGTH_SHORT).show();

return;

}

FamilyDynamicCommentDialog.this.familyDynamicView.clickCommentSend(content);

dismiss();

}

});

}

@Override

public void dismiss() {

etContent.setFocusable(false);

etContent.setFocusableInTouchMode(false);

InputMethodManager inputMethodManager = (InputMethodManager) getContext().getSystemService(Activity.INPUT_METHOD_SERVICE);

inputMethodManager.hideSoftInputFromWindow(etContent.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

super.dismiss();

}

@Override

public void show() {

super.show();

etContent.setFocusable(true);

etContent.setFocusableInTouchMode(true);

etContent.requestFocus();

etContent.post(new Runnable() {

@Override

public void run() {

InputMethodManager inputMethodManager = (InputMethodManager) getContext().

getSystemService(Context.INPUT_METHOD_SERVICE);

inputMethodManager.toggleSoftInput(0,

InputMethodManager.HIDE_NOT_ALWAYS);

}

});

}

}

FamilyDynamicView为回调接口，因为应用是mvp构造，可依据实据状况回调即可。这里通过familyDynamicView.clickCommentSend(content)来回调触发发送性能。

R.style.DialogFullScreen 让Dialog全屏。

应用

FamilyDynamicCommentDialog familyDynamicCommentPopup = new FamilyDynamicCommentDialog(this,this);

familyDynamicCommentPopup.show();
