聊天頁面鍵盤遮擋底部輸入框

好記性不如爛筆頭。

1. 在AndroidManifest.xml 中添加屬性

 <activity android:name=".chat.ChatActivity"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="adjustResize|stateAlwaysHidden" />

 

2.根佈局layout中添加屬性  android:fitsSystemWindows="true"

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:fitsSystemWindows="true"
    xmlns:tools="http://schemas.android.com/tools">

3. 點擊Recyclerview 鍵盤消失

public class TouchCloseInfutSoftMethodFrameLayout extends FrameLayout {


    public TouchCloseInfutSoftMethodFrameLayout(@NonNull Context context) {
        super(context);
    }

    public TouchCloseInfutSoftMethodFrameLayout(@NonNull Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    public TouchCloseInfutSoftMethodFrameLayout(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                KeyboardUtils.hideSoftInput(this);
                super.dispatchTouchEvent(ev);
                break;
            default:
                super.dispatchTouchEvent(ev);
        }
        return true;
    }

}

 

 <com.oversea.commonmodule.widget.TouchCloseInfutSoftMethodFrameLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:paddingTop="8dp"
        android:paddingBottom="16dp"
        android:layout_above="@+id/layout_bottom"
        android:layout_below="@+id/layout_top">

        <com.oversea.commonmodule.widget.recyclerview.LoadMoreRecyclerView
            android:id="@+id/lmr_message_list"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </com.oversea.commonmodule.widget.TouchCloseInfutSoftMethodFrameLayout>

4.私聊頁面查看歷史消息，判斷是否到頂部

mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);
                if (!recyclerView.canScrollVertically(-1)) {

                    DLog.d(TAG, " loadMore start");
                    presenter.loadMore();
                }
            }
        });

5. 私聊頁面消息的添加

@Override
    public void loadMessage(List<ChatMsgEntity> mList, boolean firstLoad) {
        if(mList == null || mList.size() == 0){
            return;
        }

        DLog.d(TAG, " loadMore loadMessage firstLoad = " + firstLoad +
                " thread = " + Thread.currentThread().getName());

        if(firstLoad){
            mAdapter.replaceData(mList);
            mRecyclerView.scrollToPosition(mDatas.size() - 1);
        }else{

            mDatas.addAll(0,mList);
            mAdapter.notifyItemRangeInserted(0,mList.size());
            mRecyclerView.scrollToPosition(mList.size() - 1);
        }
    }

6.當用戶滑動列表到中間，再次點擊輸入框。這時候需要將recycler view 滾動到最後一行。

 //底部變化後，滾動recylerview
        findViewById(R.id.layout_bottom).addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
            @Override
            public void onLayoutChange(View v, int left, int top, int right,
                                       int bottom, int oldLeft, int oldTop,
                                       int oldRight, int oldBottom) {

                if (left == oldLeft && right == oldRight && oldTop > top && oldBottom > bottom) {
                    mRecyclerView.scrollToPosition(mAdapter.getItemCount() - 1);
                }
            }
        });
