seekbar Android中的运行时错误

我已经创建了搜索栏，我想更新textview中的搜索栏值。我做了以下事情。

布局文件的一部分是

<RelativeLayout
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_weight="1.15" >

                    <LinearLayout
                        android:id="@+id/linearLayout1"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_centerHorizontal="true"
                        android:layout_marginTop="49dp"
                        android:background="@drawable/circle"
                        android:orientation="vertical" >



                        <RelativeLayout
                            android:layout_width="match_parent"
                            android:layout_height="match_parent"
                            android:layout_weight="1.90" >

                            <TextView
                                android:id="@+id/seekvalue"
                                android:layout_width="wrap_content"
                                android:layout_height="wrap_content"
                                android:layout_alignParentLeft="true"
                                android:layout_centerVertical="true"
                                android:text=" " />
                        </RelativeLayout>
                    </LinearLayout>

                    <SeekBar
                        android:id="@+id/showvalue"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_alignParentLeft="true"
                        android:layout_below="@+id/linearLayout1" />

Java代码是

text=(TextView)findViewById(R.id.seekvalue);
            // slide_me.setRightBehindContentView(R.layout.right_menu);

            slider=(SeekBar)findViewById(R.id.showvalue);
            slider.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
               // int progressChanged = 0;

                public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser){
                   // progressChanged = progress;
                    text.setText(progress);
                }

                public void onStartTrackingTouch(SeekBar seekBar) {
                    // TODO Auto-generated method stub
                }

                public void onStopTrackingTouch(SeekBar seekBar) {

                }
            });
