2 解决办法

                    <Button
                        android:id="@+id/installButton"
                        android:layout_weight="1"
                        android:layout_height="40dp"
                        android:layout_marginRight="10dp"
                        android:background="@drawable/bg_button_install"
                        style="@style/ButtonProjection"
                        android:text="@string/text_install"
                        android:textSize="19sp"
                        android:textColor="@color/colorClearBtnStart"
                        />

因为我没有提供宽度，加上宽度就可以了

                    <Button
                        android:id="@+id/installButton"
                        android:layout_weight="1"
                        android:layout_height="40dp"
                        android:layout_width="0dp"
                        android:layout_marginRight="10dp"
                        android:background="@drawable/bg_button_install"
                        style="@style/ButtonProjection"
                        android:text="@string/text_install"
                        android:textSize="19sp"
                        android:textColor="@color/colorClearBtnStart"
                        />
